The Great Mosque of Gaza is one of the largest and oldest mosques in the Gaza Strip. It is believed to have been built over the remains of a Philistine temple and later used as a church during the Byzantine period. After the Islamic conquests, it was converted into a mosque and has served as the center of religious activity in the city for centuries. The mosque is a blend of Roman, Byzantine, and Islamic architecture and is home to an expansive library housing numerous Islamic manuscripts.
