Historian have mentioned more than one hundred seljuk monuments in the small city of Damghan, unfortunately almost one half of them have been destroyed by mongols and other invaders but the remained ones are really some of the most beautiful buildings in Iran, especially these ones:
Minaret of Tari-Khana, one of the oldest and most beautiful tile works in Islamic architecture
Congregational Mosque
There are also some beautiful Mausoleums in Damghan which have been built mostly by Seljuk kings Tughril Beg, Alp Arslan and Malik Shah in 11th century, which one do you think is the most beautful?
