Hasanabad Square was built by the order of Mirza Yusef Ashtiani, the vizier of Naser ed Din Shah, and was named after his son, Mirza Hasan Ashtiani, who then became the Prime Minister of Iran for a period.

[1][2] Following the 1979 Revolution, the square was renamed to The 31st of Shahrivar, in commemoration of the invasion of Iraqi bombers to the Iranian air bases.

Once there was a statue at the square, which represented the Qajar-era constitutional activist Malek ol Motekallemin.

After the 1979 Revolution, for unspecified reasons, the statue was moved to the store of the City's Park and then completely disappeared.

[3] The surrounding buildings of Hasanabad Square were designed by Iranian-Armenian architect Qelich Baqelian, with the structural engineering provided by fellow Iranian-Armenian architect Leon Tadosian.
