Jewish families lived in Hebron, the latter having been diminished in number following the destruction of 1834. Climate Urban development Historically, the city consisted of four densely populated quarters: the suq and Harat al-Masharqa adjacent to the Ibrahimi mosque, the silk merchant quarter (Haret Kheitun) to the south and the Sheikh quarter (Haret al-Sheikh) to the north. It is believed the basic urban structure of the city had been established by the Mamluk period, during which time the city also had Jewish, Christian and Kurdish quarters. In the mid 19th-century, Hebron was still divided into four quarters, but the Christian quarter had disappeared. The sections included the ancient quarter surrounding the cave of Machpelah, the Haret Kheitun (the Jewish quarter, Haret el-Yahud), the Haret el-Sheikh and the Druze quarter. As Hebron's population gradually increased, inhabitants preferred to build upwards rather than leave the safety of their neighbourhoods. By the 1880s, better security provided by the Ottoman authorities allowed the town to expand and a new commercial centre, Bab el-Zawiye, emerged. As development continued, new spacious and taller structures were built to the north-west. In 1918, the town consisted of dense clusters of residential dwellings along the valley, rising onto the slopes above it. By the 1920s, the town was made up of seven quarters: el-Sheikh and Bab el-Zawiye to the west, el-Kazzazin, el-Akkabi and el-Haram in the centre, el-Musharika to the south and el-Kheitun in the east. Urban sprawl had spread onto the surrounding hills by 1945. The large population increase under Jordanian rule resulted in about 1,800 new houses being built, most of them along the Hebron-Jerusalem highway, stretching northwards for over at a depth of 600 ft (200m) either way. Some 500 houses were built elsewhere on surrounding rural land. There was less development to the south-east, where housing units extended along the valley for about 1 mile (1.5 km). In 1971, with the assistance of the Israeli and Jordanian governments, the Hebron University, an Islamic university, was founded. In an attempt to enhance the view of the Ibrahami Mosque, Jordan demolished whole blocks of ancient houses opposite its entrance, which also resulted in improved access to the historic site. The Jordanians also demolished the old synagogue located in the el-Kazzazin quarter. In 1976, Israel recovered the site which had been converted into an animal pen, and by 1989, a settler courtyard had been established there. Today, the
