Cannon Hall is a country house museum located between the villages of Cawthorne and High Hoyland some 5 miles (8 km) 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 (Queen Mary's Own) 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. History Although there was a house on the site when the Domesday Survey of 1086 was conducted, Cannon Hall picked up its current name from the 13th-century inhabitant Gilbert Canun. By the late 14th century Cannon Hall was in the ownership of the Bosville family of Ardsley, now a suburb in south-east of Barnsley. It was during this period that the most violent event in Cannon Hall's history took place. The Bosvilles had let the Hall out to a family (whose name has been lost), the daughter of whom was romantically involved with a man named Lockwood. Lockwood had been involved in the murder of Sir John Elland, the High Sheriff of Yorkshire. The tenant, afraid of the position in which he could find himself accommodating a fugitive, sent word to Bosville. Bosville's men arrived at Cannon Hall, where the fugitive was slain in a cruel and violent manner. Cannon Hall's history settled down after this notably unpleasant episode. In 1660 the estate was purchased by John Spencer, a Welsh hay-rake maker. The Spencer family had arrived in Yorkshire from Montgomeryshire in the Welsh borders, a safer place than Wales for those with Royalist sympathies such as those of the Spencers (John Spencer even managed to get a pardon from Charles II himself when John was held in York prison on manslaughter charges). The Spencer family became active in the local iron and coal industry - notably under John Spencer (died 1729) who took advantage of the death of his partners to establish control. The family built a huge empire and
