The Ulu Cami was the first large congregational mosque of the Ottomans. It measures 56 x 68 m over all (outside measures) and some 50 x 62 m inside. Twelve heavy piers carry the twenty middle-sized domes (diameter: almost 9 m).
Outside the hours of prayer, a multitude of different people share the mosque’s interior space: from worshippers meditating or studying the Kuran, to domestic and foreign tourists interested in art and history.
