Sládečkovo vlastivědné muzeum v Kladně, Regional museum in Kladno, Czech Republic

The Sládeček Regional Museum in Kladno is a regional institution founded in 1899. Since 2008 it has occupied a former director's villa of the Poldi steelworks, purchased when the museum came under the Central Bohemian Region in 2003. Its displays cover the prehistory of the Kladno area, the town's growth into a royal mining town, and the local castle.

The city museum was founded in 1899 on the initiative of mayor Jaroslav Hruška, its first collections made up of tombstones, paintings and sculptures from the Church of the Assumption demolished in 1897. After 1918 the Musejní spolek bought Kladno Castle from the Břevnov Benedictines, and Antonín Sládeček became the first director. Closed 1939–1945, it reopened in April 1946, became a district museum in 1954, passed to the Central Bohemian Region in 2003 and moved to a former Poldi steelworks director's villa, opened 28 March 2008.

The museum is named after a local scholar who dedicated his work to studying the region. Visitors can see everyday objects and crafts that show how people in this area lived and worked over the centuries.

The museum opens Tuesday through Sunday and requires no special preparation for a visit. Checking the website before going helps confirm current opening hours and any temporary exhibitions on display.

The museum's name honours Antonín Sládeček, its first director after the city bought Kladno Castle from the Břevnov Benedictines in the late 1920s and early 1930s; he laid the foundations for cataloguing the collections. The castle also housed the town archive and public library.
