The Gök (Blue, for the colour of its marble) or Firuz Paşa Camii (Mosque), built in 1394 by Hoca Firaz Bey, who was the Menteşe governor of Sultan Beyazid. He was a Grand Vizier of Murat, who was the father of Yıldırım Beyazid. To its west are buildings belonging to a medrese (Qu’oran School). It is also called the Kurşunı of “lead covered” mosque, because its roof is covered with that metal.

The entrance is imposing.
