The History of the Roman Drainage Canal

The Roman Drainage Canal in Jerusalem was a critical infrastructure element constructed at the end of the 1st century B.C.. This 650-meter-long underground tunnel was engineered to manage the runoff of rainwater from the Temple Mount down the Tyropoeon Valley, leading the water towards the south side of the lower city, not directly into the Shiloah pool. 

During the Great Revolt in 70 AD, the Roman Drainage Canal served as a refuge for Jewish rebels hiding from Roman forces in Jerusalem. The Romans attempted to find these rebels by breaking through the pavement into the canal, where a Roman sword and other artifacts were later discovered, evidencing their search. Historian Josephus vividly describes this tragic pursuit. In modern times, the canal was excavated in 2011, leading to significant archaeological finds including a golden bell and an engraved Menorah on a stone object near the Shiloah Pool.
