The museum building was built in 1840 as the mansion of Giridizade Mehmet Pasha, the Treasurer of Karesi Sanjak. This building, which has great historical importance because the people of Balıkesir gathered in this building the day after the occupation of Izmir and decided to fight armed struggle in Western Anatolia, was used for a long time during World War II. It was used as the Corps Headquarters. After being used as a municipal service building between 1947 and 1988, the building was restored and turned into a museum. The museum directorate was established in 1987. The museum was put into service on September 6, 1996, after the restoration and artifact collection works were completed.
