A team of archaeologists working in the ancient Jerusalem area has announced the discovery of what appears to be a prehistoric dam located near a historic pool traditionally associated with the biblical story of Jesus healing a blind man.

Researchers say the structure, made from large stacked stones and compacted earth, predates known Roman engineering in the region and may date back thousands of years. Initial surveys suggest the dam was likely built to control water flow into a nearby basin, which later became the Pool of Siloam — a site referenced in the Gospel of John as the place where Jesus told a blind man to wash his eyes before he regained his sight.

Excavation leader Dr. Miriam Halevi told reporters that the find is significant because it offers new insight into how ancient communities managed water resources in the area long before the time of Jesus.

“The construction techniques indicate a surprisingly advanced understanding of hydraulic engineering,” Halevi said. “This suggests that the pool area was carefully maintained for centuries, not just during the Roman period.”

Historians note that the Pool of Siloam has long been considered both a practical water reservoir and a religiously meaningful location. The discovery of the prehistoric dam strengthens the idea that the site held importance to earlier civilizations as well.

While the find does not prove or disprove any religious accounts, scholars say it deepens understanding of the historical setting in which biblical events were said to have taken place.

Further excavation and dating tests are expected in the coming months, as researchers work to determine exactly when the dam was built and how long it remained in use.
