Archaeologists have made a stunning—yet thoroughly puzzling—discovery in northern Israel: a 3,800-year-old Canaanite arch and stairway, perfectly preserved underground.
Researchers don’t know the purpose of the structure, which was unearthed at the Tel Shimron archaeological site. They also don’t understand why it was sealed off not long after its construction.
But its preservation is “breathtaking, especially since the building material is unfired (!) mud brick—a material that only rarely survives a long time,” says excavation co-director Mario A.S. Martin, an archaeologist at the University of Innsbruck in Austria, in an email to Live Science’s Sascha Pare.
Archaeologists haven’t historically paid much attention to Tel Shimron. Before the current dig began in 2017, the site had never been extensively excavated. Recently, the team stumbled upon a strange structure that appeared to be man-made.
“We kept digging down further, and it was preserved at a depth of one meter, then two meters, then three meters, then four meters,” excavation co-director Daniel Master, an archaeologist at Wheaton College, tells the Times of Israel’s Melanie Lidman. “This structure was totally intact, and suddenly we realized we were dealing with the foundation of a building or a superstructure that had been constructed at the top of the site.”
The team uncovered mud brick walls up to 13 feet (4 meters) thick, reports Ariel David of Haaretz. Strangely, no rooms were found within them. Instead, the inside was made up of a long corridor—which led to the mysterious arch. Beyond it, researchers found a staircase leading deeper underground.
