Especially valuable items of the historical collection are weapons, furniture and small items (such as statues of border-soldiers) and documents, dating mostly from the Military Border era (1691-1881) and, to a lesser extent, from the Turkish era (1536-1691). The collection of the Labour Movement, National Liberation War and socialist rebuilding consists of items and archive material dating from the Second World War and the post-war era. Over time, the museum has gathered diverse materials from more recent periods, up to the times of the Croatian Independence War.
