Keren Hayesod
The Jewish Agency was (and is still) housed in a fortress-like building in the Rehavia neighborhood of Jerusalem. The land for the Rehavia neighborhood had been purchased in 1922 by the Palestine Land Development Corporation, and construction of the Jewish Agency headquarters was paid for by the ZO. The three-winged structure with a large open courtyard was designed by Yochanan Rattner. Along with the Jewish Agency it also houses the headquarters of the JNF and Keren Hayesod-United Israel Appeal. On March 11, 1948, a bomb planted in the courtyard of the building by Arab militants killed 13 and wounded many others. The Keren Hayesod wing was completely destroyed. Leib Yaffe, director-general of Keren Hayesod, was among those killed in the bombing.
