Its collections include valuable exhibits in the field of painting, handicraft, folk art, archeology, and natural sciences.
The precise date the museum opened is unknown as the founding documents are lost, however the first item (a petrified tree) was written into the inventory book on 10 October 1908 by Szymon Tadeusz Włoszek (1843-1933), a veteran of the January Uprising.
[1] In 1922 the museum made an attempt to acquire the Palace of the Kraków Bishops in Kielce, however, this was unsuccessful.
During the Second World War, the museum did not operate and many items were plundered by the invaders, however Edmund Massalski managed to hide some of the collection and the museum resumed operations immediately after the way.
[1] In 1971, by the resolution of the Provincial Branch of National Council, the palace complex with adjacent buildings was transferred to the Świętokrzyskie Museum, followed by the September 18, 1971 grand opening of the first two expositions: one on the ground floor, called the Nine Centuries of Kielce; and, on the second floor: the Gallery of Historic Interiors.
