Heydarzadeh’s house is a historical mansion situated in Magsoudiyya suburb of Tabriz on the south side of Tabriz Municipality building. There is no document showing the date of construction of this historical house, but studies revealed that the house constructed about 1870 by Haji Habib Lak. The house was registered in the list of National Remains of the Country in 1999 under the number 2524. It covers an area of 900 square meters and has two floors. The building has two interior and exterior yards which are separated by house.
In the basement, there is a Howz-Khaneh (a large room with a small pool with a fountain in the middle) ornamented with colorful bricks and vault. Other parts of the house are connected together through a hall. The building was ornamented with wooden-worked windows (called Orosey), stuccoes, colorful glasses, brick works and paintings. The main room (Shah Neshin) is one of the most attractive rooms of the house.
Heydarzadeh's house was restored in 2001, and is currently used as Tourism Information Center of East Azerbaijan province and Tabriz.
