In 1951 City Museum Celje founded a department for the history of the National Liberation Struggle. After a decade of intensive progress the department developed into an independent cultural institution – Museum of Revolution Celje – in 1963. Its premises were in the building of the former Celje city hall (the city hall was in this building between 1830 and 1953), where it presented the history of Celje and its region from 1918 to 1945, and in the Old Pot, Celje prison, where 374 hostages were shot during the occupation in World War II.
