Jerusalem: wooden beams from the First Temple resurface after 2,600 years

They had been there for 2,600 years, exactly where the roof collapsed. Carbonised wooden beams uncovered in the City of David in Jerusalem represent one of the most striking discoveries in Near Eastern archaeology in recent years. Preserved - paradoxically - by the very fire that destroyed them, they could allow researchers to establish an unprecedented timeline for the end of the First Temple period, razed by the Babylonian army in 586 BCE.¹

A dig in the depths of the City of David

The discovery was made at the Givati Parking Lot excavation, at the heart of Jerusalem Walls National Park, just a few metres south of the Old City. This site, excavated since 2007 jointly by the Israel Antiquities Authority (IAA) and Tel Aviv University, has proven one of the richest in the country: every sedimentary layer superimposes centuries of uninterrupted occupation, from the Bronze AgeBronze AgeA protohistoric period following the Neolithic, defined by bronze metallurgy (a copper-tin alloy) and the rise of the first cities and states; in Egypt it corresponds to the age of the first pyramids.→ to the Byzantine period.

Archaeologists uncovered the beams within a thick destruction layer dating to the turn of the sixth century BCE. The building that housed them has not yet yielded all its secrets, but its layout suggests the presence of an inner courtyard covered by a wooden roof. When flames engulfed the building, that roof collapsed onto the courtyard floor, where it remained - intact in its initial configuration - for more than two and a half millennia.²

The paradox of the preserving fire

How can wood survive more than 2,600 years in the ground? The answer lies in a counter-intuitive phenomenon: it was the fire itself that ensured the beams' preservation. When the flames charred the building, the plaster from the walls melted and flowed over the collapsed timbers, encasing them in a mineral shell. Hardening as it cooled, this plaster formed an airtight sealSealA small engraved object (often steatite) used to stamp a mark in clay; the Indus seals, bearing animals and signs, attest to administration and trade, though their script remains undeciphered.→ that protected the wood from moisture, wood-boring insects and oxygen for centuries.

In Israel, ancient wood is exceedingly rare in excavation. The Mediterranean climateClimateThe long-term average atmospheric conditions of a region; its variations (glaciations, aridifications) shaped migrations, agriculture and the collapse of prehistoric societies.→ - hot summers, wet winters - is particularly hostile to the preservation of organic materials. The decade preceding this discovery had yielded only a handful of isolated wood fragments, never such a coherent and substantial ensemble. "Finding well-preserved wood in Israel is exceptional," IAA officials stated in their 20 July 2026 press release. "Here we have large beams with visible growth rings - a scientific resource with no equivalent for this period."³

There is more: after the 586 BCE destruction, when survivors gradually reclaimed the city and began rebuilding, they often left the rubble of former buildings in place rather than clearing it away. New structures rose above, sealing the destruction layer under several metres of fill. It is this preserved stratigraphyStratigraphyThe study of the superimposed layers (strata) of an archaeological site; each layer corresponds to a phase of occupation and yields a relative chronology.→ that allowed the beams to be found in exactly the position in which they had fallen.

Dendrochronology to the rescue

The true scientific contribution of this discovery lies in the dating possibilities it offers. Carbonised wood retains its growth rings - those concentric circles each tree forms annually, whose width varies according to that year's climatic conditions. By comparing them to reference sequences established for the Mediterranean and Near EastNear EastA region of western Asia (Levant, Mesopotamia, Anatolia, Iran), cradle of the Neolithic revolution, agriculture, the first cities and writing.→, researchers can date a piece of wood with precision that radiocarbon dating alone cannot achieve.

Radiocarbon dating, though indispensable, produces for this period results with uncertainty margins of up to several centuries. The Givati Parking Lot beams, by contrast, display an exceptional number of visible rings, which should allow researchers to date their felling to within a decade, or even less. In time, researchers hope to build a precise chronology for the First Temple period - a pivotal era in Judaean history for which absolute archaeological data is still lacking.⁴

A remnant of the Babylonian catastrophe

To grasp the significance of this discovery, one must recall the historical context. In 605 BCE, Nebuchadnezzar II, king of the mighty Neo-Babylonian Empire, established himself as the undisputed master of the Near East following the Battle of Carchemish. In 597, he marched on Jerusalem, seized the city and deported a first wave of Judaean elites to Babylon. King Jehoiakim was replaced by Zedekiah, now a Babylonian vassal.

When Zedekiah rebelled, Nebuchadnezzar returned. The second siege of Jerusalem lasted eighteen months. In July 586 BCE, the walls fell. The city was sacked, Solomon's Temple - the First Temple - put to fire and sword. The population was massively deported. This event - one of the major turning points in ancient Near Eastern history - is what the carbonised beams witnessed, endured, and memorialised within their fibres.⁵

Archaeological evidence for this catastrophic episode had until now been scattered and varied in nature: arrowheads, ashes, amphora fragments, charred administrative bullae. The beams represent the most substantial and best-preserved organic remains found to date for this precise event. Their study, which will continue for several years, should make it possible to identify the tree species used in construction - Lebanese cedar, pine, sycamore? - and to reconstruct the timber supply networks of First Temple-period Jerusalem.

Towards a new chronology of the First Temple

The First Temple period remains one of the most difficult to date precisely in Near Eastern history. Textual sources - the Bible, Assyrian and Babylonian inscriptions - provide a narrative framework, but absolute dates, those that allow a biblical event to be corroborated with an archaeological stratum, are often lacking or contested among specialists.

The Givati Parking Lot beams fit into a broader research programme aimed at calibrating the "high" and "low" chronology of the Iron AgeIron AgeThe last period of protohistory (from c. 1200 BC in Europe and the Near East), marked by iron metallurgy and the first kingdoms.→ in Israel - a scholarly debate that has divided different schools of thought since the 1990s over the settlement patterns and nature of the kingdoms of Judah and Israel. A piece of timber datable to within a few years, contemporary with a historical event as well attested as the fall of Jerusalem in 586 BCE, constitutes an exceptional chronological anchor.

Published just days before Tisha B'Av - the fast day commemorating the destruction of both Temples - the discovery aroused strong emotion beyond the academic world alone. It is a reminder that history sometimes chooses to speak through its most unexpected silences: that of charred wood, asleep beneath centuries of rubble, and awakened today by the brushes of archaeologists.⁶
