English: Built for Shehzade Mustafa, son of Mehmet the Conqueror. Mustafa died in 1474, his remains after some travels were brought to Bursa, to be buried in the mausoleum of an uncle, until in 1479 this mausoleum was built for him and he was buried here. Another son of Mehmet, Cem Sultan, died in 1499, was buried in the same mausoleum, which led to it today being called Cem Sultan Mausoleum. Its decoration is part with Iznik Tiles (turquoise and dark blue hexagons with in their centre and at the edges zoomorphic motifs), part with hand-drawn ornaments which for a long time were covered with 19th century baroque ornaments, but were uncovered during a 2013 restoration.
