A huge and quite simple structure with no dome but a normal pitched roof, the Sultan Murad (or Hunkar) Mosque dates from 1463 and is the oldest surviving mosque in the city. Built on the site of a monastery destroyed by the Ottomans, the mosque has been burnt down several times during its long history but retains many old features. Outside are two türbe (mausoleums) and several gravestones. Note that at the time of our last visit in the spring of 2018 the building was receiving a serious makeover and was almost impossible to visit.
