On the island of Khadir, in the Indian state of Gujarat, the ruins of Dholavira still raise their stone ramparts above a landscape that seems so inhospitable as to forbid all life. And yet, for nearly fifteen centuries, a prosperous city thrived here, perhaps home to several thousand inhabitants, girded by walls and irrigated by a water network of astonishing ingenuity. Dholavira is today regarded as one of the best-preserved sites of the Indus CivilisationIndus CivilisationA major Bronze Age urban civilisation (c. 2600-1900 BC) across present-day Pakistan and north-west India: planned cities (HarappaHarappaA major city of the Indus Civilization, in the Pakistani Punjab, the first site excavated and the one that gave the Harappan culture its name.→, Mohenjo-daroMohenjo-daroOne of the largest cities of the Indus Civilization (Sindh, Pakistan), famed for its Great Bath and grid layout; a World Heritage site.→), standardised bricks, undeciphered script, no monumental palaces.→, and its inscription on the UNESCO World Heritage List in 2021 confirmed its exceptional importance [1].
What strikes the visitor at once is the contrast between the harshness of the setting and the refinement of the urban organisation. Where one would expect to find the fragile remains of a makeshift camp, one discovers a city conceived down to its smallest details: concentric enclosures, a dominant citadel, rigorously laid-out quarters, drainage systems, and above all this obsession with water that runs through the entire history of the site.

Over the course of this article, we shall explore the singular geography of the island of Khadir and the reasons why a city could come into being there; the history of the site's discovery and of the excavations that revealed its wealth; the seven phases of occupation that punctuate fifteen centuries of history; the tripartite urbanism so characteristic of Dholavira; the hydraulic genius that makes it a global case study; the mysterious "signboard" and the undeciphered script of the Indus; the economic and craft life of its inhabitants; the funerary rites of its necropolis; and finally, the slow decline of the city under the combined effects of aridification and the upheavals that struck the entire Indus Civilisation.
The fortified zone of the site covers roughly forty-seven hectares, which by its size makes it the fifth largest known Harappan site, after Mohenjo-daro, Harappa, Ganweriwala and Rakhigarhi. But size is not everything: it is the quality of preservation, the massive use of stone and the coherence of the overall plan that give Dholavira its exceptional character. Where other cities were partly devoured by the recovery of their bricks over the millennia, or buried under alluvium, Dholavira has crossed time with an almost architectural clarity, offering archaeologists a plan legible down to its smallest lanes.
A city in the desert
To understand Dholavira, one must first understand the place that gave rise to it. The island of Khadir, or Khadir Bet, is a rocky outcrop of about 2,000 square kilometres rising out of the Great Rann of Kutch, that immense salt expanse stretching over thousands of square kilometres in the northwest of the Indian subcontinent. During the dry season, the Rann is a desert of cracked salt, blindingly white, swept by wind and heat. During the monsoon, it partly turns into a brackish marsh, isolating the rocky islands like so many rafts of stone. It was on the northwestern corner of one of these islands that the Harappan builders chose to establish their city, at a spot where two seasonal watercourses, the Manhar and the Mansar, frame a rocky promontory [2].
This choice of location may seem paradoxical. Why found a city in so hostile a setting, where fresh water is scarce, where agricultureAgricultureThe cultivation of plants and production of food by working the soil, which emerged in the Neolithic in the Near East and independently elsewhere; it radically transformed human societies.→ seems impossible and where salt impregnates even the water table? The answer lies in several converging factors. First, the island offered a precious raw material: a local stone, sandstones and limestones easy to extract and to carve, which allowed the Harappans of Dholavira to build in stone where most other cities of the Indus, such as Mohenjo-daro or Harappa, built mainly in unbaked and baked brick. This particularity partly explains the exceptional state of preservation of the site.
Next, and above all, Dholavira occupied a strategic position on the trade routes. At the time of its peak, the Rann of Kutch was not the desert it has become: it was probably a marine gulf or a vast navigable body of water connected to the Arabian Sea. Dholavira thus controlled a point of passage between the interior of the continent and the maritime routes, between the sources of raw materials in Gujarat, Sindh and Rajasthan, and the distant markets of Mesopotamia and the Persian Gulf. The city was a trading post, a hub of exchange through which passed shells, semi-precious stones, copper and manufactured goods [1].
Finally, the builders had identified a decisive resource: the runoff of the two seasonal streams that framed the site. Rather than depending on a permanent river, as most great ancient cities did, Dholavira would base its survival on the capture, storage and management of rainwater. It is this constraint that, paradoxically, gave rise to the hydraulic genius of the city, turning a handicap into an architectural signature.
Discovery and excavations
The site of Dholavira takes its name from a neighbouring modern village. Locally, the ruins were known as Kotada Timba, "the great mound of the fort", which says much about the popular memory of the place: the villagers had long known that these mounds covered the remains of an ancient, fortified town. It was in 1967-1968 that the Indian archaeologist Jagat Pati Joshi, of the Archaeological Survey of India, formally identified the site as belonging to the Indus Civilisation, bringing it to the attention of the scientific community [3].
But it was from 1989 onward that Dholavira would yield its most precious secrets, under the direction of another ASI archaeologist, Ravindra Singh Bisht. Over thirteen excavation campaigns, until 2005, Bisht's team methodically uncovered the structures of the city, revealing its tripartite plan, its monumental reservoirs, its fortifications, and a whole series of objects that would transform the understanding of the Indus Civilisation. These excavations revealed that Dholavira was not a minor site on the Harappan periphery, but one of the major cities of the Indus world, comparable in scale and organisation to the great centres of Mohenjo-daro, Harappa, Ganweriwala and Rakhigarhi [2].
The work of Bisht and his team was remarkable for its stratigraphic rigour. By carefully distinguishing the successive layers of occupation, the archaeologists were able to reconstruct a fine chronology of the life of the site, from its humble beginnings to its abandonment, by way of its monumental peak. This sequence of seven phases, which we shall detail below, constitutes one of the major contributions of Dholavira to the study of the Indus Civilisation, for few sites offer such a continuity of occupation documented over so long a period.
The excavations brought to light treasures of information: engraved seals, pottery, beads, cubic stone weights, copper tools, fragments of script, and above all the remains of a hydraulic engineering of a scale unmatched in the Indus world. Each discovery confirmed that Dholavira had been a leading urban centre, endowed with a sophisticated administration, skilled craftspeople and builders mastering advanced techniques. It was on the strength of these results that UNESCO finally inscribed the site as World Heritage in 2021, stressing that it represents one of the most remarkable and best-preserved examples of urban planningUrban planningThe planned organisation of urban space (streets, districts, water and drainage networks, public buildings); the Indus Civilisation offers an early and remarkable example.→ of antiquity [1].
The inscription as World Heritage was, moreover, no formality. The nomination of Dholavira, championed by the Indian authorities and the Archaeological Survey of India, put forward three great criteria: the exceptional testimony that the site provides about the Indus Civilisation, its role as an eminent illustration of an urban ensemble and an architectural landscape, and its remarkably sophisticated water-management system. The World Heritage Committee, meeting in July 2021, recognised that Dholavira constituted a particularly complete and well-preserved example of a Harappan city, making this site one of India's heritage properties tied to prehistory and to the great ancient cultures to receive this distinction.
The seven phases of occupation
The history of Dholavira was no long and tranquil river. Archaeologists have distinguished there seven successive cultural phases, designated from phase I to phase VII, covering a chronological span of about three thousand to one thousand five hundred years before our era. This sequence tells of the birth, flowering and then decline of a city, with its ruptures, its reconstructions and its adaptations. It is one of the rare Indus sites to present so complete a stratigraphyStratigraphyThe study of the superimposed layers (strata) of an archaeological site; each layer corresponds to a phase of occupation and yields a relative chronology.→, which makes it a reference for establishing the general chronology of the Harappan civilisation [2].
Phase I corresponds to the origins, around 3000 to 2900 BCE. A small community of the early Harappan horizon settles on the promontory and begins to erect structures in brick and stone. Already, the inhabitants display a sense of organisation and undertake the first defensive arrangements. The material culture of this phase links Dholavira to the pre-urban Harappan world, the one that precedes the flowering of the great planned cities.
Phases II and III, between roughly 2900 and 2600 BCE, see the consolidation of the settlement. The fortifications grow stronger, the occupation extends, the population increases. It is during these phases that the fundamental elements of the urban plan that will characterise Dholavira are put in place. A certain prosperity sets in, founded on craft and nascent trade. At the end of phase III, an episode is interpreted by some researchers as a catastrophe, perhaps an earthquake, which damaged the structures of the town and necessitated major reconstructions.
Phase IV, around 2600 to 2450 BCE, marks the threshold of the golden age. Dholavira enters the mature, or urban, Harappan period, that of the peak of the Indus Civilisation. The city reaches its full extent, its tripartite plan unfolds in all its splendour, the reservoirs are dug and built, the monumental walls rise. This is the time when Dholavira becomes a true regional metropolis, a centre of power, craft and exchange radiating across the whole of Gujarat and beyond.
Phase V, which extends to around 2100 or 2000 BCE, prolongs this peak while beginning subtle changes. The monumental splendour is maintained, but one already perceives the first signs of a mutation. It is the great classical period of the city, the one that has yielded most of the prestigious objects and the most impressive structures.
Phase VI corresponds to a rupture. Around 2000 BCE, the city seems to experience a decline or even a temporary abandonment. The urban structures deteriorate, the population diminishes. This crisis is not peculiar to Dholavira: it is part of the great upheaval that strikes the entire Indus Civilisation at the transition between the mature and the late Harappan periods.
Finally, phase VII, until around 1500 BCE, sees a reoccupation of the site by a population with different characteristics. The inhabitants of this last phase no longer rebuild the monumental city of old: they settle in more modest structures, often of circular plan, testifying to a transformed way of life, perhaps more pastoral. This late culture, sometimes linked to regional facies such as that of "Cemetery H" or to later traditions, marks the end of the Harappan occupation of the site before its definitive abandonment.
The tripartite urbanism
If Dholavira holds a place apart in the archaeology of the Indus, it is largely thanks to its urban plan. Where Mohenjo-daro and Harappa present a bipartite organisation, with a high citadel and a lower town, Dholavira is distinguished by a tripartite, even quadripartite, structure of remarkable geometric rigour. The city is composed of three great nested and hierarchised ensembles: the citadel, the middle town and the lower town, the whole enclosed within a vast rectangular enclosure [1].
The citadel constitutes the heart of power. It is the highest, most massively fortified and best-defended part of the city. It is itself subdivided into two adjoining enclosures: the "castle", surrounded by walls of impressive thickness, reaching some fifteen metres at the base, and the "bailey", a second adjacent fortified space. These ramparts, made of stone and unbaked brick, constituted a defensive system of a scale without equal in the Indus world. The citadel doubtless housed the residences of the ruling elite, the administrative buildings and perhaps ceremonial functions.
The middle town formed a second enclosure situated to the north of the citadel. It too was protected by walls and organised according to a regular plan, with streets crossing at right angles. There one probably found the dwellings of an intermediate class, perhaps officials, merchants and well-off craftspeople. Its presence, distinct from both the citadel and the lower town, testifies to an elaborate social stratification and a highly considered conception of spatial hierarchy.
The lower town, finally, extended over the largest area and accommodated the bulk of the population and of activities. It was there that the workshops, the production zones and the popular dwellings were concentrated. The whole of these three quarters was enclosed within an outer rectangular perimeter wall, several hundred metres long on each side, which made Dholavira one of the vastest fortified cities of the Indus Civilisation. Between the walls and within the quarters ran the reservoirs and channels, integrated into the urban fabric as an essential component of collective life.
This tripartite organisation, with its careful geometry and studied proportions, reveals an urban planning of great maturity. Archaeologists have noted that the dimensions of the various spaces obeyed precise mathematical ratios, suggesting the existence of a measurement system and of a true architectural doctrine. Dholavira did not grow by chance: it was conceived, thought out, measured, as the built expression of a social and cosmic order.
The quality of the construction itself must also be stressed. The builders of Dholavira mastered the art of assembling stone and brick, of raising thick and stable walls, of carving regular blocks and of arranging monumental gateways flanked by side chambers. Some of these gateways, including the famous north gate of the citadel, were genuine works of architecture, equipped with columns, worked thresholds and defensive arrangements. The use of polished stone columns, of which circular fragments have been found, even suggests a certain decorative refinement, rare in the Indus world and testifying to the high status of the city.
It is also worth recalling the sheer scale of the labour involved. Building and maintaining tens of kilometres of stone walls, excavating reservoirs into solid bedrock, dressing thousands of blocks and organising a coherent network of channels demanded not only technical skill but a sustained collective effort over generations. Such an undertaking implies a community capable of mobilising labour, planning works over the long term and transmitting specialised knowledge, a degree of social coordination that places Dholavira among the most accomplished urban experiments of the third millennium BCE.
The genius of water
If there is one domain in which Dholavira surpasses all the other cities of the Indus, it is indeed that of water management. In an environment where rain falls only a few weeks a year, where the watercourses flow only during the monsoon and where the water table is brackish, the survival of a great city was possible only at the price of an absolute hydraulic mastery. The builders of Dholavira rose to this challenge with a brilliance that still compels the admiration of contemporary engineers [1].
The fundamental principle was the capture of runoff. The two seasonal streams, the Manhar and the Mansar, that framed the site were dammed by dams and dykes that diverted their waters toward the city. This runoff, swollen by the monsoon rains, was channelled, directed and finally poured into a vast system of reservoirs. The city was literally girdled and traversed by a series of storage basins, some of which reached monumental dimensions: several dozen metres long, several metres deep, carved directly into the rock or built with extreme care.
A great number of these reservoirs have been recorded at Dholavira, distributed all around the city and within it. One of the most impressive, uncovered to the east of the citadel, was a rectangular basin carved into the stone, with stairs descending toward the bottom, recalling the stepped wells (stepwells) that would later make the glory of Gujarat's architecture. Water was conveyed from one reservoir to another by a network of channels, conduits and carefully arranged drains, allowing the resource to be distributed and avoiding both waste and flooding. Some researchers estimate that up to ten percent of the city's area was devoted to these hydraulic infrastructures.
This water engineering was not limited to storage. Dholavira also had wells, some dug into the rock, and a system of wastewater drainage that ran through the quarters, testifying to the concern for hygiene common to all the great cities of the Indus. But what truly distinguishes Dholavira is the scale and the coherence of the whole: these were not piecemeal arrangements, but an integrated hydraulic system, conceived at the scale of the entire city, designed to transform scarcity into managed abundance. At a time when the climateClimateThe long-term average atmospheric conditions of a region; its variations (glaciations, aridifications) shaped migrationsMigrationsLong-distance movements of populations; a major driver of human history (the exit from Africa, the peopling of continents, Neolithic and steppe expansions).→, agriculture and the collapse of prehistoric societies.→ of the region was probably already beginning a slow drift toward greater drought, this mastery of water was the very condition of the existence and prosperity of the city.
For specialists of water and sustainable development, Dholavira has become a reference. Here is a Bronze Age society that, without mechanical technology, without pump or motor, knew how to harvest and conserve the water of an arid environment with an efficiency that many regions of the contemporary world might envy. The city illustrates a timeless truth: in dry lands, civilisation is built drop by drop, and water there is worth more than gold.
The "signboard" and the Indus scriptIndus scriptA system of about 400 signs engraved on Harappan seals, tablets and pottery, undeciphered to date for lack of a bilingual text.→
Among the most famous finds of Dholavira is an object unique of its kind, which archaeologists have nicknamed the "signboard" or board of signs. It is a monumental inscription composed of ten large signs of the Indus script, each measuring about thirty centimetres in height, which was fixed above one of the main gates of the citadel, on the northern side. The signs were made of pieces of gypsum inlaid in a wooden panel, which decomposed, leaving the characters collapsed on the ground but preserved in their original order [2].
This panel is exceptional on more than one count. It is, first, to this day, one of the oldest monumental "signboards" known to humanity: a public inscription, visible from afar, placed at the entrance of a city, perhaps to proclaim its name, its status, or a protective formula. The size of the signs, their careful arrangement and their strategic placement above a gate suggest an official, almost proclamatory function, very different from that of the small engraved seals usually found on Indus sites.
But the "signboard" of Dholavira shares with all the other written documents of the Indus Civilisation a fundamental enigma: its scriptWritingA system of conventional signs used to fix language or information durably; its appearance (c. 3300 BC) marks, by convention, the end of prehistory.→ has never been deciphered. The Indus signs, of which several hundred variants have been recorded, appear on thousands of seals, tablets, pottery and various objects, but no one today knows what they mean or what language they recorded. The inscriptions are generally very short, only a few signs, which considerably complicates attempts at deciphermentDeciphermentThe reconstruction of the meaning and value of the signs of an unknown script, often from bilingual texts, repeated proper names or statistical regularities.→. For want of a bilingual text comparable to the Rosetta Stone, and for want of knowing the underlying language, the Indus script remains one of the great mysteries of world archaeology.
The Dholavira panel, with its ten signs, constitutes in this respect a precious document, for it offers a relatively long sequence, presented in a monumental and public context. Researchers have seen in it, by turns, a place name, a title, a dedication, without any hypothesis being confirmed. Whatever the case, this mute testimony reminds us that the Indus Civilisation, despite its urban and technical refinement, jealously guards the secret of its speech. The inhabitants of Dholavira wrote, counted, administered, traded, but their voice remains inaccessible to us, suspended in those characters that we contemplate without understanding them.
Economic life and crafts
Dholavira was not a city turned in on itself: it was a dynamic economic centre, integrated into the vast exchange networks of the Indus Civilisation and beyond. Its strategic position, at the interface between the continent and the maritime routes, made it a hub of trade. The excavations revealed an intense craft and commercial activity that structured the life of the inhabitants and explained the prosperity of the city [2].
One of the flagship crafts of Dholavira was bead making. The city produced beads of semi-precious stones, notably carnelian, agate and shell, cut, drilled and polished with great skill. These beads, objects of prestige and adornment, were exported to the other cities of the Indus and as far as Mesopotamia, where they are attested in royal tombs. The mastery of the drilling of carnelian, an extremely hard stone, using stone drills and abrasives, testifies to a remarkable technical know-how.
The craft of shell also held an important place. The proximity of the sea provided shells worked into bracelets, inlays and various objects. Traces of copper working, pottery production, weaving have also been found at Dholavira, as well as carefully calibrated cubic stone weights, which attest to the existence of a standardised measurement system common to the whole of the Indus Civilisation. These weights, which follow a rigorous binary and decimal progression, guaranteed the fairness of transactions and reveal a sophisticated commercial administration.
Long-distance trade is attested by numerous indices. Indus seals, manufactured objects and raw materials circulated between Dholavira, the other Harappan cities and the contemporary civilisations of the Persian Gulf and Mesopotamia. The city doubtless imported copper, steatite and other materials, and exported its beads, its worked shells and perhaps agricultural or textile products. This insertion into an exchange network of continental and maritime scope largely explains the wealth and influence of Dholavira during its golden age.
As for subsistence, it rested on a combination of agriculture, livestock and probably fishing. Despite the aridity, the inhabitants cultivated cereals adapted to the environment, such as millet, and grazed herds of cattle, sheep and goats. Water management, by enabling irrigation and watering, supported this subsistence economy. The whole sketches the portrait of a complex society, at once agricultural, artisanal and mercantile, capable of taking advantage of a constraining environment with constant ingenuity.
The organisation of production moreover reveals an advanced division of labour. The craft zones, identified in the lower town, show a concentration of specialised activities: here the bead workshops, there the working of shell, elsewhere metallurgy or pottery. This specialisation presupposes a society in which economic roles were differentiated and coordinated, in which craftspeople could devote themselves fully to their trade because the community collectively ensured subsistence and security. It is the sign of an already complex economy, going beyond the stage of village self-sufficiency to enter that of urban specialisation.
Necropolis and rites
Like any city, Dholavira had its dead, and the necropolisNecropolisA large organised burialBurialThe intentional deposition of a body, sometimes with offerings; a marker of symbolic behaviour.→ ground, a "city of the dead", often spanning several periods.→ that extends to the west of the city offers precious insight into the beliefs and funerary practices of its inhabitants. This funerary zone, located outside the urban enclosure, has yielded a great variety of burial structures, the study of which reveals an uncommon diversity of rites [2].
One of the most striking features of the Dholavira necropolis is the predominance of funerary structures without a body. Many tumuli and cenotaphs have been uncovered that contained no human remains, but only offerings, pottery or symbolic objects. These commemorative monuments, sometimes elaborate, suggest a form of memorial or symbolic cult distinct from burial proper. Some of these tumuli presented complex circular plans, with chambers and internal arrangements that recall the architecture of the monumental tombs of other cultures.
Burials of different types have also been brought to light: inhumations, deposits of bones, hemispherical structures. This variety probably indicates a diverse population, perhaps stemming from different cultural traditions, or else funerary practices evolving over the phases of occupation. Unlike certain contemporary civilisations, the Harappans of Dholavira do not seem to have accompanied their dead with ostentatious riches: the funerary furnishings remain relatively sober, in keeping with the egalitarian and functional spirit that characterises the whole of the Indus Civilisation, where one finds neither lavish royal tomb nor pyramid.
This funerary sobriety, combined with the absence of clear representations of rulers or of monumental deities, feeds one of the great debates on the Indus Civilisation: that of the nature of its power and of its social organisation. Everything, at Dholavira as elsewhere, seems to indicate a remarkably organised society, endowed with a sophisticated administration and planning, but strangely discreet on the level of individual glorification. The dead of Dholavira, in their often empty tumuli, speak to us of complex beliefs that we only glimpse, and that add still further to the mystery of this civilisation.
Decline and aridification
Every city knows its twilight, and Dholavira was no exception. After more than a millennium of prosperity, the great metropolis of the island of Khadir entered a long phase of decline that led, around 1500 BCE, to its definitive abandonment. The causes of this fall are many and intertwined, but one of them dominates all the others: climate change and the increasing aridification of the region [2].
During the second millennium before our era, the entire Indus Civilisation went through a profound crisis. The great cities, Mohenjo-daro, Harappa and the others, saw their populations decline, their urban organisation unravel. The causes of this general decline are still debated, but palaeoclimatologists have highlighted a degradation of climatic conditions, marked by a weakening of the monsoon and a tendency toward drying. This climatic drift affected agriculture, reduced water resources and weakened the already precarious balance of the Indus societies.
For Dholavira, situated in one of the most arid environments of the whole Harappan world, the impact was particularly severe. The city, whose entire prosperity rested on the capture of seasonal runoff, found itself directly threatened by the diminution of the rains. As the monsoon weakened, the reservoirs filled less, the streams flowed more rarely, and the so ingenious hydraulic system reached its limits. At the same time, the gradual withdrawal of the sea or the gulf that made the Rann navigable little by little cut Dholavira off from its maritime trade routes, removing the other pillar of its wealth.
The decline can be read in the archaeology of the site. From phase VI onward, around 2000 BCE, the monumental city deteriorates. The great structures are no longer maintained, the occupation contracts. Phase VII sees a more modest reoccupation, with those circular dwellings that contrast with the geometric splendour of former times. The new inhabitants live in the ruins of the defunct city, leading an existence doubtless more rural and pastoral, until the site is finally abandoned. The great climatic episode known as the 4,200-year event, which marked a major drought on a hemispheric scale, may have played a role in this collapse, as it did in the decline of other great contemporary civilisations.
Thus Dholavira faded away, not in the violence of a conquest, but in the slow stifling of an environment that was drying up. The city that had known, for centuries, how to push back the limits of the arid, ended by succumbing to the worsening of that same constraint. Its history is that of a prolonged dialogue between a society and its environment, a dialogue in which human ingenuity long triumphed before yielding to the magnitude of climate change.
Conclusion
Dholavira is not one ruin among others. Set in the middle of the salt desert of the Rann of Kutch, it embodies, perhaps better than any other site, the genius and the fragility of the Indus Civilisation. The genius of a tripartite urbanism of mathematical rigour, the genius of stone walls that have defied four thousand years of erosion, and above all the genius of a mastery of water that turned a desert into a metropolis. Fragility, too, of a society that, however brilliant it was, remained suspended on the caprice of the rains and on the slow breathing of the climate.
Inscribed on the UNESCO World Heritage List in 2021, Dholavira today offers researchers an open book on fifteen centuries of Harappan history, from the first villages to the final abandonment. Its seven phases of occupation, its mute "signboard", its monumental reservoirs and its enigmatic necropolis nourish a reflection that extends far beyond the framework of archaeology. For at the moment when our own societies face the prospect of climate disruption and of growing tensions over water, the history of this desert city resonates with a strange topicality.
Beyond its ecological dimension lies a considerable heritage significance for contemporary India. Dholavira is today a place of memory and national pride, an anchor point of the long history of the subcontinent, and a site that draws researchers and visitors from all over the world despite its geographical isolation. Its conservation, in a hostile and remote environment, remains a permanent challenge taken up by the teams of the Archaeological Survey of India, guardians of the transmission of this treasure to future generations.
The inhabitants of Dholavira have left us a lesson that we cannot yet read in their script, but that their stones state clearly: in dry lands, civilisation is an art of water. As long as they knew how to gather and keep it, the city lived and prospered. When the rain grew scarce, even the most ingenious of systems could not prevent the end. Dholavira, a dead city at the heart of the salt, thus remains one of the most striking testimonies of what humanity can achieve, and of what it cannot, in the last resort, avoid.
