The Israeli government intends to approve a plan for the rehabilitation of an ancient reservoir that once supplied water to Jerusalem, but has fallen into disrepair, Prime Minister Netanyahu and Mayor Moshe Lion announced on Monday.

Netanyahu and Lion visited the Mamilla Pool, a unique historical site from the Byzantine period, which reflects the city’s complex history.

Mamilla Pool, with a capacity of 30,000 cubic meters (some 7.9 million gallons), is located outside the walls of the Old City about 710 yards northwest of Jaffa Gate in the center of the Mamilla Cemetery. It is connected by an underground channel to Hezekiah’s Pool in the Christian Quarter of the Old City.
