Archaeologists from the Israeli Antiquities Authority and Tel Aviv University, conducting excavations in the City of David, have unearthed massive wooden beams burned during the destruction of the First Temple in 586 BCE.
The research team behind the discovery notes that the huge wooden support beams, which were surprisingly well preserved for ancient wood structures, allow for much more precise dating of the site. The researchers also highlight the apparently deliberate efforts by the city’s rebuilders to leave the ruins in place for future generations to witness.
2,600-Year-Old Wooden Beams Preserved by Melting Plaster
According to a statement emailed to The Debrief, the ancient, charred wooden beams discovered within the Jerusalem Walls National Park were relics from a collapsed building destroyed by “the intense fire of the First Temple’s destruction” over 2,600 years ago.
“The beams appear to have served as the roof of an inner courtyard in a building from the First Temple period,” explained Excavation Director Efrat Bocher.
Although not unprecedented, the team said that finding intact wood relics of this advanced age is rare, since organic materials like wood typically break down over such extended time periods. In this case, they suggest that the surprisingly intact beams were likely preserved by melting plaster, “sealing the burnt wood beneath.”
“During the destruction, they collapsed onto the floor,” Director Bocher explained. “We believe that the plaster cladding of the building’s walls, melted by the fire, covered the charred wooden beams, and ultimately enabled their exceptional preservation.”
Growth Rings Help Archaeologists Narrow the Site’s Dating Range
When discussing the historic and scientific value of the discovery, Dr. Johanna Regev of the Israel Antiquities Authority, who studied the wooden beams up close, noted the exceptional rarity of finding ancient wood with “such a large number” of visible growth rings.
“Here, in the City of David, we found thick beams with many rings, offering significant research potential,” Dr. Regev said.
For example, the researcher explains, more growth rings help scientists date sites and materials with increased precision and “higher dating resolution.”
“Until now, we could date finds within a range of hundreds of years,” Dr. Regev explained. “Now we can attain much greater precision, narrowing the dating range down to as little as ten years.”
City’s Rebuilders Left Ruins in Place as a “Testament to the Destruction”
While the historic site was witness to a tragic destruction, the research team said returning residents beginning to rebuild the city appear to have intentionally left the remains untouched for future generations to see.
“[They] probably made a deliberate decision to preserve the memory of the destruction by leaving behind remains that tell the story of the catastrophe,” the team explained.
Dr. Yiftah Shalev, who directs the excavation on behalf of the Israel Antiquities Authority alongside Prof. Yuval Gadot of Tel Aviv University, said the idea of a landscape of memory is “familiar from many cultures around the world.”
“Preserving memory is a human need, seeking to preserve what once existed,” Dr. Shalev explained. “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.”
On a more personal note, Director Bocher noted the serendipitous timing of the discovery “just before Tisha B’Av.” According to Hillel.org, the holiday, which is recognized as the saddest day on the Jewish calendar, “is a day of mourning for tragedies across Jewish history, most particularly the destruction and loss of the first and second Temple and Jerusalem.”
“This discovery makes you feel that you are witnessing the very moment of destruction, the moment when it all happened,” the researcher concluded, adding that “it’s deeply moving.”
