It is said that when Kılıç Ali Pasha asked Sultan Murat III for land in order to build a mosque, he was told that he should build the mosque on the sea, as he was told that he should boult the mosque on the sea, as he was the kaptan pasha. Thus, Kılıç ALi Pasha had the mosque built on reclaimed land. There is a fountain in the courtyard, the dome of which rests eight marble columns. The mosque is seen to be smaller verison of Hagia Sophia, and is in a rectangular shape. The hurricane lamp that used to hang from the 16th century on was transferred to the Naval Museum in 1948. On the right of the mosque there is a single minaret with a single balcony. The tomb of Kılıç Ali Pasha is in the courtyard, lying in the direction of Ka’ba. There is a fountain by the garden wall that face the street. The Turkish baths are on the right side of the mosque and are still used today. The madrasa is located on the side ofthe mosque that faces the sea.
