The Gazi Husrev Beg Mosque (Bosnian Husrev-begova džamija, Turkish Gazi Hüsrev Bey Camii), also shortened to Begova Mosque (Begova džamija) from 1530/31 (building inscription) in Sarajevo is the largest and one of the oldest mosques in Bosnia and Herzegovina Herzegovina.
It was built on behalf of Gazi Husrev Beg (Turkish: Hüsrev Beğ/Bey), a nephew of Sultan Bayezid II during the period of the court architect Acem Esir Ali (also: Alaüddin, Acem Alisi), the predecessor of the famous Mimar Sinan. As with many other major projects of the time, craftsmen from Ragusa (Dubrovnik) were also involved in the construction.
