On the north side of the Har Habayis, in the eastern part, there is a large pool, called by the Arabs Birket Isra'in, a corruption of Birket Beni Israil, pool of the sons of Yisroel. It is first mentioned by this name by Muqadassi, an Arab geographer, in the tenth century. There are different opinions about its date, with some dating to Herodian times, and some dating it to later times, like when the Romans rebuilt Yerushalayim as a pagan city, called aelia capitolina, during the times of Hadrian yemach shemo. Towards the end of the 19th century, the pool was being used as a garbage dump, as well as a vegetable garden. In 1934 the pool was filled in because its condition posed a threat to public health. In 1981 a small square equipped with benches was constructed on part of the covered pool. Today the area is known as el-Ghazali Square, and is used as a parking lot, as well as a collection point for garbage, before it is dumped outside the city. Some small shops also exist at the site.

  Above the ground, the northeast corner of the (expanded) Har Habayis can be clearly seen, and to the north of it is the more modern eastern city wall of Yerushalayim. However, underground the Har Habayis wall does not end at this point, but runs further, for another 38.4 meters (126 feet).

   Warren writes the following about this (Survey of Western Palestine, Jerusalem, pp 129-130): Gallery along east wall of Sanctuary, Commenced 5th June,1869. From a point (P) 18 feet south of the north-east angle, a gallery was driven along the wall (level 2,363 feet 3 inches [720.31 m]) to north, past where the straight joint between the Castle of Antonia and city wall should occur; but no straight joint was found to exist. The wall runs on without a break of any kind, and there is no projection... To a distance of 65 feet (19.81 m) the stones were all like those at the Wailing Place, but beyond this to 75 feet (22.86 m) they had rough projecting faces (projections about 6 to 10 inches [15-25 cm]) with well-cut marginal drafts.
