The Hosseinieh Ershad or Hosseiniyeh Ershad (Persian: حسینیه ارشاد) is a religious institute in Tehran, Iran. It was closed for a time by the Pahlavi government in 1972. The institute is housed in a large, domed hall, and is used for lectures on history, culture, society, and religion. The Hosseiniyeh Ershad was built by a member of the very prominent Homayounfar family.
The facility also includes a large public library, where most of its users are college students.
Dr. Ali Shariati held his anti-Pahlavi speeches here before the revolution. Mir-Hossein Mousavi (under the psuedonym Hossein Rah'jo) and Zahra Rahnavard exhibited artwork here during the same period. [1]
