Conisbrough Castle is a 12th-century castle in Conisbrough, South Yorkshire, England, whose remains are dominated by the 97-foot (29.5m) high circular keep, which is supported by six buttresses. In the mid-1990s, the keep was restored, with a wooden roof and two floors being rebuilt. Audio and visual displays now help to reconstruct a view of life in a medieval castle, while a history of the site is documented in the adjacent visitors' centre. The building is considered one of South Yorkshire's primary tourist attractions, and sees in excess of 30,000 visitors per year. It is managed by English Heritage, as of 1 April 2008. Doncaster Council own the land the monument is standing on, but English Heritage manages the property.
