Much treasure has survived from the Seljuk period in Damqan. Pir-e Alamdar's Shrine (The Old Flagbearer's Tomb), Congregation Mosque, the minaret of Congregation Mosque, Tarikhaneh Mosque, Mansourkuh, Imamzadeh Jafar Tower and Chehel Dokhtaran Vault, etc. are buildings in which Islamic architecture from Seljuk period onward is notable. For the first time in Iran these buildings carry brick decorations to compensate for the monotonous and uniform rows.
