Hasanabad, Tehran

Hasan Abad is an old and traditional business area within the Moniriyeh district of Tehran, Iran.

The area was originally developed during the Qajar dynasty, when they were beautifying the capital Tehran. There is also a square in the area which carries the same name. The square was composed of four identical buildings (see image), each covering one corner of the square. They were built by Ghelidj Baghelian (Persian: قليچ باقليان ) and his engineer Leon Tadossian (Persian: لئون تادوسيان ), famous Armenian architect. The name of this square comes From Mirza Hassan Mostowfi ol-Mamalek The prime minister Of Iran .

Following the Iranian Revolution in 1979, the square was renamed to "31st of Shahrivar Square", however the new name did not stick and it is still known as the "Hassan Abad Square".

Following the revolution, the Iranian Cultural Heritage Organization (ICHO) re-constructed several of the buildings in the Hassan Abad square. However as part of the reconstruction they added two additional modern floors onto the old structure.
