The Sombor City Museum is a complex heritage museum that performs the activity of collection, preservation, publication and exhibition of the cultural heritage of the area of the city of Sombor and the municipalities of Apatin, Kula and Odžaci. The activity of the Museum is organized through the activities of the archaeological, ethnological, historical and the fine arts department, as well as the activity of the special museum library and the conservatory department.

The Sombor City Museum has two annexes within the Historical department:

The museum collections are increased by archaeological excavations, field research, exchange, gifts, legacies, transfer of materials from the closed institutions and museum purchases. During its several decades long activity, the Sombor City Museum has accepted numerous legacies from important people, such as Dr Imre Fraj, painters Zoran Stošić Vranjski and Mileta Vitorović, the gymnast Tereza Kočiš, the Vuić family and others. The total museum fund consists of around 40.000 museum items from all areas of museum activity.
