Hezekiah's Tunnel Constructed

Around 701 BCE, with an Assyrian invasion looming, King Hezekiah ordered an underground tunnel to channel water from the Gihon Spring to the Pool of Siloam inside Jerusalem's walls. Two teams of workers dug from opposite ends and met in the middle — a remarkable engineering feat. The Siloam Inscription, discovered in 1880, describes the emotional moment of breakthrough. You can still walk through the tunnel today, ankle-deep in water.
