English: 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 mosque is rather small (which was okay for a ‘provincial’ foundation) but has a grand portico and rich carving. This thick and deepset portico as a feature of Bursa type mosques achieved a sense of power and grandeur in the provinces. Here it is matched by the forcefulness of the design of chevrons incorporated into the arches.
