5. The Christian Quarter is in the northwestern part of the city, between the Jaffa and Damascus Gates, in the picture. Its most important locality is the Church of the Holy Sepulchre, where tradition has fixed the scenes of the crucifixion and resurrection. The church is a group of buildings, crowned with a dome, and erected at various periods. The Holy Sepulchre itself is a marble shrine within the cathedral, 26 feet long, by 18 broad, and 20 feet high. If the ancient wall can be certainly shown not to have been _outside_ of this place, then the identity of the holy places may be deemed measurably sure, since the cross and the sepulchre were undoubtedly near the wall, but without it. Another place of interest is the Muristan, a ruined castle, which was the headquarters of the Knights Hospitallers during the Crusades. V. =Fountains and Pools.= Most of these are without the walls, and only one is shown in the picture. The identification of the ancient pools is not easy, and explorers are not agreed with regard to their position and modern name. 1. The _Birket Mamilla_, supposed by many to represent the Upper Pool of Gihon (2 Kings 18:17; Isa. 7:3), lies 2,000 feet west of the Jaffa Gate, and is now 240 feet long by 144 wide, but anciently much larger. 2. The _Birket es Sultan_, supposed to be the Lower Pool of Gihon, where Solomon was crowned (1 Kings 1:38), lies just outside the southwestern corner of the wall, in the Valley of Hinnom. It is narrow, but 500 feet long. 3. The _Birket es Silwan_, or Pool of Siloam (John 9:7), is in the Tyropoeon Valley, near its junction with the Kedron Valley, just outside the limit of the picture, on the left. It is 52 feet long, and 18 wide. 4. The _Birket el Hamra_ ("red pond") lies south of the Pool of Siloam, still further outside of the picture, and is larger, but now nearly filled up, and without water. Some think that this is the pool dug by Hezekiah. (2 Chron. 32:30.) 5. The spring _En-rogel_, called by Christians the Fountain of the Virgin, and by Moslems _'Ain Umm ed Deraj_ ("the spring the mother of steps," from the 28 steps leading down to it), is the only natural fountain near the city. It lies in the narrowest part of the Kedron Valley, opposite the stone Zoheleth. (1 Kings 1:9.) Its action is intermittent, rising and falling suddenly, sometimes oftener than once a day. From this fact, some have thought it to be the Pool of Bethesda. (John 5:2-9.) 6. But most of the explorers regard the Pool of Bethesda as identical with the _Birket Israel_, which may be found on the picture just within the eastern (foreground) wall, between the gate of St. Stephen and the northern wall of the Temple Enclosure, just behind the little domed building by the wall, to the left of St. Stephen's Gate. This is 360 feet long, by 120 feet wide, and 80 feet deep, but half filled with rubbish. 7. The _Birket Hamman_ ("Pool of the Bath"), generally known as
