Birket Israel (trans. Pool of Israel) also Birket Israil or Birket Isra'in, abbreviated from Birket Beni Israìl (trans. Pool of the Children of Israel) was a public cistern located on the north-eastern corner of the Temple Mount, in Jerusalem. The structure is believed to have been built by the Romans for use as a water reservoir and also to protect the northern wall of the Temple Mount. Arab locals have known it by this name since at least 1857.
