Water System in Tel Megiddo

Getting water is a problem for this fortress. The only spring lies outside the fortress walls. In the 9th century BCE, King Ahab constructed a massive water system with a 30 meter deep shaft and a 70 meter long tunnel.

This tunnel was hewn from both ends at the same time (like Hezekiah's Tunnel) and its builders were only one foot off when meeting in the middle.
