This Seljuk era mosque is a beautiful example of the fine architecture of the 14th century. Its tall outer walls enclose a large arcaded courtyard leading to a double-domed prayer hall. 

The large columns of black granite used in the structure were recycled from the Roman baths. Above the richly decorated main entrance is an elaborate calligraphic inscription. 

Dated January 10, 1375, it identifies Ali, son of Mushimish al-Damishki, as the architect. Visitors are welcome to visit the interior outside of prayer times.
