Hızır Çavuş Mosque

Hızır Çavuş Mosque, a mosque built in the Ottoman period located in the Balat neighbourhood of the Fatih district of Istanbul province. It is also known as Çavuş Mescidi and Sefer Çavuş Mescidi. The exact construction date is unknown. It was commissioned after the conquest by Hızır Ağa, the divan sergeant of Mehmed II. It burned in the Great Balat Fire of 1854 and was rebuilt by a philanthropist. In 1963-64 it underwent repair as reinforced concrete. In the inner courtyard of the mosque there is the tomb of Hızır Çavuş and, next to the mosque, a Quran course with the same name.

It has a single minaret. The minaret is a single balcony. The building, constructed of stone, is covered with a flat tiled roof. Its interior and exterior walls are coated with cement plaster. The pulpit and lectern are wooden, the mihrab is marble.

In Ekrem Hakkı Ayverdi's *Ottoman Architecture in the Fatih Era* the tomb in the mosque courtyard is said not to belong to Hızır Ağa, while in Tahsin Öz's work *Istanbul Mosques* the mosque's name and patron are given as "Sefer Çavuş".
