This area in Jerusalem is not so much a museum as it is an archaeological and historical experience. The City of David is largest archaeological site in Jerusalem today at attracts about 500,000 visitors a year. Within the City of David are many ancient archaeological finds including Hezekiah's Tunnel and Warren's Shaft. Both the tunnel and the shaft were used as defense mechanisms against potential invaders of the city walls. In ancient Israel, there were not many sources of water. Hezekiah's tunnel was used to redirect the water source underground so that it could not be contaminated by enemies.
Visitors can experience both Warren's Shaft and Hezekiah's tunnel. Both tunnels are not lit, so a flashlight will be necessary. A visitor can peer down into the incredible darkness of the shaft or hike a mile in Hezekiah's tunnel where the water can reach waist-level.
The City of David offers a peek into ancient Israeli history, and it can all be experienced first-hand.
