In 1951, Israel Military Industries built a munitions factory on some of the land that became Ramat Beit HaKerem. It closed down in 1997,[1] but environmental groups say the ground is polluted with toxic chemicals despite clean-up attempts.[2] Ramat Beit HaKerem, Beit HaKerem, Givat Beit HaKerem, and Yefeh Nof neighborhoods are sometimes considered one "ultra neighborhood" called "Beit HaKerem Rabati" (lit. Greater Beit HaKerem).[3] The master plan for the neighborhood includes 2,500 apartments.[4]
