Suleyman himself (1550s) - perhaps the most splendid of all Ottoman türbes - and that of his wife Hürrem Sultan, with some extremely fine tilework.

Konya In Konya the grounds of the 12th-century Alâeddin Mosque contain two conical-roofed early türbes containing the remains of members of the Seljuk Rum dynasty. The town is also home to the türbe of Jalal ad-Din Muhammad Rumi, which is a major shrine and pilgrimage point. In Konya, as in Kayseri, türbes are also referred to as Kümbets. Bursa The Ottoman capital before the conquest of Constantinople in 1453, Bursa is home to the türbes of most of the earlier sultans including Osman I and his son, Orhan. Türbes in the grounds of the lovely Muradiye Complex contain the remains of Murad II and several princes. The Yeşil Türbe (Green Türbe), a large three-story tower in the grounds of the Yeşil Mosque, houses the beautifully tiled sarcophagus of Mehmed I. Much of its exterior is covered with plain blue tiles, despite the name of the tomb suggesting that they are green.

The türbe of Haji Bektash Veli is located in the original Bektashi tekke (now a museum) in the town that now bears his name and remains a site for Alevi pilgrims from throughout Turkey.
