Archaeologists have uncovered charred sycamore wood preserved for 2,600 years. The growth rings inside may allow researchers to date the destruction to within a single decade.
Beneath a parking lot in the City of David, archaeologists from the Israel Antiquities Authority and Tel Aviv University have uncovered massive charred wooden beams believed to date to one of the most consequential moments in the history of ancient Jerusalem: the destruction of Solomon’s Temple by the Babylonian king Nebuchadnezzar II in 586 BC.
The announcement came on July 20, 2026 — days before Tisha B’Av, the Jewish fast day that commemorates the destruction of both Temples.
What was found
The beams appear to have formed the roof of an inner courtyard in a First Temple-period building. When the building was destroyed, the roof collapsed onto the floor. Melted plaster from the walls then covered the charred wood, creating the conditions that allowed the beams to survive for approximately 2,600 years. The wood has been identified as sycamore — a timber commonly used in ancient Judah for major construction.
This is, in fact, the second time that roof beams from this specific building have been found at the Givati Parking Lot excavation site. The first discovery came from the building’s southern section; this new find comes from a different part of the same structure — suggesting the building was large, significant, and almost entirely destroyed in the Babylonian fire.
Alongside the beams, as the Times of Israel reported, archaeologists also found a collection of artifacts consistent with life in First Temple-period Jerusalem: pottery, storage vessels, and administrative objects that together paint a picture of an ordinary building in a city on the eve of catastrophe.
The science: Dating to within a decade
What makes this discovery scientifically extraordinary is the unusual number of growth rings preserved in the wood. Dr. Johanna Regev, a radiocarbon dating expert at the IAA, said: “It is very rare in Israel to find wood with such a large number of growth rings. Here, in the City of David, we found thick beams with many rings, offering significant research potential — with more growth rings enabling higher dating resolution. Until now, we could date finds within a range of hundreds of years. Now we can attain much greater precision, narrowing the dating range down to as little as ten years.”
As Phys.org explained, the beams represent a rare opportunity for dendrochronological analysis — the scientific dating of wood using growth rings — in a region where preserved ancient timber is extraordinarily scarce. If the dating succeeds, it would provide one of the most precise archaeological timestamps ever achieved for events of the First Temple period.
Memory preserved in ruins
Researchers believe Jerusalem’s residents likely chose to preserve the memory of the destruction by deliberately leaving the ruins in place. Excavation director Yiftah Shalev said: “Preserving memory is a human need, seeking to preserve what once existed. Here we see it in its clearest form: a deliberate choice to leave ruins in place as a testament to the destruction and build the new layer over them.”
The detail is quietly remarkable. The people who returned to Jerusalem after the Babylonian exile did not clear away the rubble. They built over it, layer upon layer, leaving the evidence of what had happened sealed beneath them — a stone and timber testimony to an event that had shattered their world and that their descendants would commemorate annually, for millennia, on Tisha B’Av.
Solomon's Temple, built in the 10th century BC as the permanent home of the Ark of the Covenant, was the spiritual center of ancient Israel. Its destruction in 586 BC by Nebuchadnezzar II — following a siege that the Book of Kings and the Book of Jeremiah both describe in detail — marked the beginning of the Babylonian exile and ushered in what scholars call the Second Temple period, the era in which Jesus himself would later live and worship. The destruction of the Second Temple by Rome in 70 AD is commemorated on the same fast day — Tisha B’Av — as the destruction of the First.
The full analysis of the beams is ongoing. A peer-reviewed publication is expected later this year.
