The Tomb of Cem Sultan was built for Şehzade Mustafa, the son of Sultan Mehmed the Conqueror. Şehzade Mustafa passed away near Niğde in 1474, and his body was first brought to Konya, then to Bursa, where he was buried in his uncle Alaaddin Bey’s tomb. In 1479, he was reburied in this tomb, which was constructed for him. Later, Cem Sultan (the son of Sultan Mehmed the Conqueror), who died in Naples and was brought to Bursa in 1495, was also buried here. Therefore, the tomb is known today as the “Tomb of Cem Sultan.” The interior walls are covered with tiles and feature elaborate ornamental details. The 16th-century structure, which was adorned with Baroque decorations in the late 19th century, was restored in 2013 by scraping the plaster and reviving it.
The walls are covered with turquoise and cobalt blue hexagonal tiles, decorated with gilded rumi motifs in the center of the tiles. The four marble sarcophagi inside belong to Şehzade Mustafa, Cem Sultan (died 1495), and Sultan Bayezid I’s sons Şehzade Abdullah (died 1485) and Şehzade Alemşah (died 1503). Between 2013 and 2014, the tomb underwent extensive restoration by the Bursa Metropolitan Municipality and was included among the structures designated as UNESCO World Heritage sites in 2016.
