Richmond Castle in Richmond, North Yorkshire, England, stands in a commanding position above the River Swale, close to the centre of the town of Richmond. It was originally called Riche Mount, 'the strong hill'. The castle was constructed by Alan Rufus from 1071 onwards following the Norman Conquest of England, and the Domesday Book of 1086 refers to 'a castlery' at Richmond.
In the 12th century, his great-nephew Conan expanded the castle and built the keep. Although it was derelict by 1540, it was restored centuries later. The property is the best-preserved early Norman castle in England and an important tourist attraction.
