The Kılıç Ali Pasha Mosque is located in the Tovani district of Istanbul, and was commissioned by the Ottoman Admiral Kılıç Ali Pasha, and was built by the architect Sinan in 1580. It was designed as a complete mosque complex, which includes the mosque itself, a school, a mausoleum, a public fountain, a school and a bathroom. The original plans for the mosque are one of the rare intact 16th-century documents that show how Sinan worked to make the mosque resemble the Hagia Sophia.
