Gazanfer-bey mosque

The Gazanfer-bey Mosque, also known as Gazanferija, stands in Banja Luka in Republika Srpska, Bosnia and Herzegovina, on the right bank of the Vrbas River. Belonging to the Islamic and Ottoman architectural tradition, it is listed among the National Monuments of Bosnia and Herzegovina. The mosque takes its name from Gazanfer Bey, who is recorded as voivode and za'im of Banja Luka. It was destroyed in 1993 during the war and has since been the subject of reconstruction.

The mosque's inscription has not survived, so the date of construction is not certain. One source gives 1578 as the year of building, while another dates it to the late 16th century on the basis that Gazanfer Bey was a contemporary of Gazi Ferhad Pasha and Defterdar Hasan Efendi.

Gazanfer Bey was close to Ferhad Pasha, and his signature on the Ferhad Pasha endowment deed shows that he served as voivode and za'im of Banja Luka. He also signed the endowment deed of Sefer Sipahi.

The mosque was destroyed in 1993 during the Bosnian War. Sources describe its reconstruction as under way.
