Dönenler Mosque
It was built in the 14th century as the semahane of the Mevlevihane. This first Mevlevi Lodge of Kütahya, one of the original examples of Early Anatolian Turkish architecture, was repaired twice and the semahane and dervish cells have survived to the present day. The building, which is used as a mosque today, has a rectangular plan and an octagonal pulley. Adjacent to the building, the masjid built by Imadüttin Hezar Dinari, known as the "Conqueror of the Seljuk Period of Kütahya", became the tomb of the Mevlevihane with the burial of Ergun Çelebi, the grandson of Mevlana. The semahane was converted into a mosque by adding a mihrab in subsequent repairs. It is popularly known as Dönenler Mosque. There is a 19th century tile inscription on the entrance door of the mosque.
