Ottoman architecture
The old Latin Carmelite church was converted into the Sarayönü Mosque, also known as the Orduönü Masjid (). Its exterior displayed arched Gothic architecture, while its interior reflected classical Ottoman architecture. The Sarayönü madrasa, a cemetery, a bazaar, law courts, a fountain, coffeehouses, an arsenal, a military hospital, coffeehouses, a Turkish bath and the Ottoman qadi's residence were built during the Ottoman period in the square. However, as the city's population grew, the military facilities were relocated outside the city and houses with classical Ottoman architecture, featuring bay windows were built.
