View of the Süleymaniye Complex in Istanbul that features a large mosque with four minarets that was designed and built by Sinan, the architect of Suleiman the Magnificent.
Note the three structures this side of the mosque. The structure closest to the mosque is where the Tomb of Suleiman is located. The one in the middle is the Tomb of his wife Roxelana. The structure on the wall is the Dal–ül Kuran—a place where the proper reading of the Koran was taught.
