Ras Abu 'Ammar is thought to have been established in the 19th century.[6]
The nearby Kh. Kafr Sum have remains from the Crusader era, including a court-yard building and rock-cut cisterns. A tower to the south east was later turned into Maqam ash-sheikh Musafar.[7]Victor Guérin noted that: "There are a lot of rickety houses, which are built of small, almost unhewn stones, near one waly, which stands in the shade of a mulberry tree of several hundreds years old. Not far from it there is a semicircle swimming pool, built in a crude way". And further: "A large structure, partly built of ancient stones with typical projection, served as a mosque, as we can tell from the presence of the mihrab in it. It is very likely that the structure had stood before the Muslims settled here, and they just adopted it for their cult".[8]
The SWP described it as "a small stone village on a hill; to the east in a small valley is a good spring, with a rock-cut tomb beside it."[9]
Ottoman era
In 1838, both et-Ras and Kefr Sur were noted as villages in the el-Arkub district, southwest of Jerusalem.[10][11]
In 1863 Victor Guérin was pointed out on a mountain the small village of Ras Abu 'Ammar, which high position had given its name.[12]
An Ottoman village list from around 1870 showed that Ras Abu Ammar had 6 (?) houses and a population of 92, though the population count only included men.[13][14]
In 1883, the PEF's Survey of Western Palestine (SWP) described Ras (Abu 'Ammar) as "a large stone village on a spur, with a fine spring in the valley to the north-west. The hill has only a little scrub on it, but the valley, which is open and rather flat, has olives in it."[15]
In 1896 the population of Ras Abu 'Ammar was estimated to be about 279 persons.[16]
In the 1945 statistics, the village, with a population of 620 Muslims,[2] had 8,342 dunams of land according to an official land and population survey.[3] Of the land, 925 dunams were plantations and irrigable land 2,791 were for cereals,[19] while 40 dunams were built-up (urban) land.[20]
The village was depopulated on October 21, 1948.[4] The area was later incorporated into the State of Israel and the village of Tzur Hadassah was established on Ras Abu 'Ammar land in 1960.[5]
In 1992 the village site was described: "The stone rubble of the village houses is strewn across the site. Wild vegetation grows among the debris, in addition to almond, olive, and carob trees. Cactuses grow on the southeastern and southwestern sides of the site; a two-room stone building that used to be the schoolhouse still stands to the southeast."[5]
