The Suleymaniye Mosque is located on the Sultan Ahmet district, historically perhaps the most important part of Istanbul, from which the Ottoman sultans ruled the world and where today are first-class historical buildings. This extraordinary mosque is the second largest Istanbul mosque. It is one of the most visited places in Istanbul. It was built by the famous Ottoman architect Mimar Sinan on the orders of Sultan Suleyman the Magnificent in the 16th century.
In this complex of mosque buildings (Turkish: "Külliye") are the mausoleum of sultan Suleiman the Magnificent and the architect Sinan himself, cemetery, the guard building, the astronomical observatory, the madrasah, the hamam, the well, the public kitchen and many other facilities. The kitchen continues to function and helps those who need it the most. This architectural complex was a novelty for the Islamic world at the time and its harmony is an extraordinary feature of Turkish construction.
