Cannon Hall is a country house museum located between the villages of Cawthorne and High Hoyland some 5 miles west of Barnsley, South Yorkshire, England. Originally the home of the Spencer and later the Spencer-Stanhope family, it now houses collections of fine furniture, paintings, ceramics and glassware. It at one time housed the Regimental Museum of the 13th/18th Royal Hussars and the Light Dragoons, which has now closed. Now occupying four rooms in the east wing is the "Family of Artists" exhibition on loan from the De Morgan Foundation, which draws on the links between the Spencer Stanhopes and the De Morgans.The building is constructed of coursed sandstone with ashlar dressings with a symmetrical layout of a central 3-storey block of 5 bays and slightly set back 2-storey side wings of 3 bays.
