The Süleymaniye Mosque is an Ottoman imperial mosque located on the Third Hill of Istanbul, Turkey. It is the largest mosque in the city, and one of the best-known sights of Istanbul.
The Süleymaniye was ravaged by a fire in 1660 and was restored by SultanMehmed IV. Part of the dome collapsed again during the earthquake of 1766. Subsequent repairs damaged what was left of the original decoration of Sinan (recent cleaning has shown that Sinan experimented first with blue, before turning red the dominant color of the dome).
