Tzrifin
Tzrifin (Hebrew: צְרִיפִין) is an area in Gush Dan (Dan Region) in central Israel, located on the eastern side of Rishon LeZion and including parts of Be'er Ya'akov. The area proper is defined as an 'area without jurisdiction' between the two cities.
Nearly the entire area of Tzrifin proper is taken up by the central Israel Defense Forces base, Camp Yigael Yadin (a.k.a. Camp Tzrifin, Camp 782), with which it is synonymous, even though the base also spills into Rishon LeZion and Be'er Ya'akov. Camp Yadin contains a multitude of training bases, as well as Prison Four, the largest Israeli military prison.
History
Tzrifin was founded in 1917, during World War I, as a British base named Sarafand, after the nearby Arab village Sarafand al-Amar. Sarafand was a central British base in a strategic location, having a railway connection to Jaffa and Lydda (Lod). The Transjordan Frontier Force (TJFF) was established at Sarafand on 1 April 1926 with a cadre drawn from the Arab Legion. The TJFF subsequently moved to Zerqa in October 1926. During World War II, the Jewish Brigade was formed in Tzrifin.
