It has been removed from maps and airbrushed from aerial photographs. But Facility 1391 certainly exists - you just have to ask the Palestinians and Lebanese who have been imprisoned and tortured there.
Facility 1391 has been airbrushed from Israeli aerial photographs and purged from modern maps. Where once a police station was marked there is now a blank space. Sometimes even the road leading to it has been erased. But Israel's secret prison, inside an army intelligence base close to the main road between Hadera and Afula in northern Israel, is real enough. For 20 years or more it has been housed in a large, imposing, single-storey building designed by a British engineer, Sir Charles Taggart, during the 1930s as one of a series of garrison forts designed to contain growing unrest in Palestine. Today, the thick concrete walls and iron gates are themselves protected by a double fence overseen by watchtowers and patrolled by attack dogs.
