Conisbrough Castle is defined by its unique 12th-century circular keep, which features six massive buttresses supporting the structure. Built by Hamelin Plantagenet, the half-brother of Henry II, the fortress served as a high-status residence rather than a purely defensive military outpost. The site is widely recognized for its association with Sir Walter Scott’s 1819 novel, Ivanhoe, which immortalized the location in literature. Extensive restoration efforts in the 1990s preserved the internal masonry and the upper chambers, allowing visitors to access the wall walk and the restored chapel.
