Inside the mosque, which lies in the southeastern corner of the complex. Originally built in 1207 by the Seljuk, but re-modeled by the Ottomans in 1511; the shape of the mihrab, and the marble minber date from that time.

Mihrab = a semicircular niche in the wall of a mosque that indicates the direction of the Kaaba in Mecca and hence the direction that Muslims should face when praying. The wall in which a mihrab appears is the "qibla wall."
Minber = a pulpit in the mosque where the imam (prayer leader) stands to deliver sermons.
