Çeltik Ulu (Central) Mosque which is one of the interesting examples of late Ottoman architecture in Anatolia, was built of stone with a square plan. The other units of the structure which were  designed as a complex have not survived to the present day. The harim part of the mosque, which was built in 1815 as a foundation work, has a plan with nine domes carried by four pillars.  To the north of the harim section, a transverse rectangular planned last congregation extends. The last congregation place is entered through a triple opening and the opening in the middle is emphasized with a triangular pediment. The structure's single-balcony minaret which is made of cut stone material , is located in the northwest corner, at the junction of the harim and the last congregation place.
