Mamilla Pool

Mamilla Pool is one of several ancient reservoirs that supplied water to the inhabitants of the Old City of Jerusalem. It is located outside the walls of the Old City about 700 yards northwest of Jaffa Gate in the centre of the Mamilla Cemetery. With a capacity of 30,000 cubic metres, it is connected by an underground channel to Hezekiah's Pool in the Christian Quarter of the Old City. It was thought as possible that it has received water via the so-called Upper or High-Level Aqueduct from Solomon's Pools, but 2010 excavations have discovered the aqueduct's final segment at a much lower elevation near the Jaffa Gate, making it impossible to function as a feeding source for the Mamilla Pool.

There are a number of theories on the origin of the name Mamilla. John Gray writes that it may be a corruption of the Hebrew word for 'the filler' (m'malle'), though that is uncertain. Others indicate it may have been named for its sponsor, Mamilla or Maximilla, or for a church that once stood near the pool that was dedicated to a saint named Mamilla or Babila.

The pool's original date of construction is unknown.

Following the Persian capture of Jerusalem from the Byzantines in 614, a large number of Christians were massacred at the pool.

During the period of Crusader rule over Jerusalem in the 12th century, Mamilla pool was known as the Patriarch's Lake, and the Pool of Hezekiah inside the city walls that it fed was known as the Pool of the Patriarch's Bath.

In the 19th century, Horatio Balch Hackett described the pool:

At the distance of several hundred yards we come to another pool, Birket el-Mamilla, generally supposed to be the Upper Gihon of Scripture, (Isaiah 36, 2.) This reservoir is still used, and on the ninth of April contained three or more feet of water. It is about three hundred feet long, two hundred wide, and twenty feet deep. It has steps at two of the corners, which enable the people not only to descend and fetch up water, but to lead down animals to drink. It is customary, also, to bathe here.

After the 1948 Arab-Israeli war, the Jerusalem municipality temporarily tried to connect the pool to the Jerusalem water supply, and coated the pool with cement.
