With a tall octagonal, truncated minaret and six vaults, the Menüçer Camii was built by the Seljuk Turks in 1072. The blend of Armenian and Seljuk design resulted from the Seljuks employing Armenian architects and artisans. Distinctive features are the red-and-black stonework, and also the polychrome stone inlays adorning the ceilings. The minaret sports an Arabic inscription: bismillah ('in the name of Allah'). Climb the dingy spiral staircase inside for excellent views. There's no parapet so take care.
Nearby is an excavated area, containing remains of houses, with ovens, a granary and bathrooms. The structure next to the mosque may have been a Seljuk medrese or palace.
