The Yörgüç Paşa Camii was built in 1428, on initiative of Yörgüç Paşa, a Beylerbeyi (= ‘Leader of leaders’, this means: regional governor) and vizier of sultan Murat II. The mosque has no minaret; just a small wooden tower, from where the muezzin can call for prayer. The building was restored in 1976.
On the picture: the northern façade of the mosque. (From left to right): the blind wall of a room not connected with the prayer hall; the small hallway where the main entrance is; the ‘open türbe’ of Yörgüç Paşa.
(From Wikipedia): A muezzin is the person appointed at a mosque to lead, and recite, the call to prayer for every event of prayer and worship in the mosque. The muezzin's position is an important one, as he is the one responsible for each call to prayer. The community depends on him for accurate prayer schedules).
