The Süleymaniye Mosque (Turkish: Süleymaniye Camii, pronounced [sylejˈmaːnije]) is an Ottoman imperial mosque located on the Third Hill of Istanbul, Turkey. The mosque was commissioned by Suleiman the Magnificent (r. 1520–1566) and designed by the imperial architect Mimar Sinan. An inscription specifies the foundation date as 1550 and the inauguration date as 1557, although work on the complex probably continued for a few years after this. The Süleymaniye Mosque is one of the best-known sights of Istanbul and from its location on the Third Hill it commands an extensive view of the city around the Golden Horn. It is considered a masterpiece of Ottoman architecture and one of Mimar Sinan's greatest works. It is the largest Ottoman-era mosque in the city. Like other Ottoman imperial foundations, the mosque is part of a larger külliye (religious and charitable complex) which included madrasas, a public kitchen, and a hospital, among others. Behind the qibla wall of the mosque is an enclosed cemetery containing the separate octagonal mausoleums of Suleiman the Magnificent and his wife Hurrem Sultan (Roxelana). The Süleymaniye Mosque and its Associated Conservation Area is one of the four components of the UNESCO World Heritage Site "Historic Areas of Istanbul", protected under cultural criteria (i), (ii), (iii), and (iv). Located within the Historic Peninsula, the site falls under multiple conservation designations: it was nationally registered in 1981 as an urban and historic conservation area and again in 1995 as an Archaeological, Urban Archaeological, Historical and Urban Site. The area contains 920 registered properties, including monumental and civil architecture.
