Towhid Prison (in Persian: بازداشتگاه توحید) is an unofficial detention centre in Tehran, Iran. The word towhid refers to one of the five pillars of Islam, monotheism. It reportedly was shut down in August 2000 after Roozbeh Farahanipour presented his report on the prison to Amnesty International and other human rights organizations [1] [2].
Before 1979 it was known as Anti Vandalism Common Committee.
Currently it is Warning Museum (Ebrat Museum) of Tehran.
