Avicenna Mausoleum

Designed by Hooshang Seyhoun, it was built in 1952, replacing an older building dedicated to Avicenna which was destroyed in 1950.

The Pahlavi government had plans to build the mausoleum since at least 1939. The mausoleum was eventually dedicated in a grand ceremony in May 1954, and the avenue running in front of it was also renamed in honor of Avicenna.

As the monument was a central element of the propagation of Iranian nationalism by the Pahlavi government, it was consequently in danger of being defaced, but as Khomeini himself was an admirer of Avicenna, the square was not renamed after the 1979 Revolution.
