Initially this museum was created as a museum of the Revolution of September 1951, but with all the Communist accent from the beginning, the museum has a collection consisting of various valuable exhibits, representing the rich history of the entire region. Since 1991, the institution has been transformed into a true historical museum. Inside, the museum has the following sections: archeology, ethnography, history of Bulgaria centuries XIV-XIX, modern history, current history and cultural heritage. The museum presents to the tourists valuable discoveries from the Neolithic era, the Thracian age, the Roman era, the Middle Ages and the Renaissance period of Bulgaria. A special value is represented by the Yakimov silver treasure, a copy of which is displayed here. The museum’s exhibits are placed in various locations in the town of Montana, such as the Exhibition Hall, Mihailov House, the Lapidarium Archaeological Exhibition and the Ancient Fortress.
