A 15th Century castle was one of the first to be built from brick. It is a former home of the Royal Observatory (from 1946) and now part of The International Study Centre of Queen’s University (Ontario).
The drummer may be associated with the story of Lord Dacre who would constantly beat his drum to drive would be suitors from his much younger wife. Eventually she decided to lock him a small room and left him there to starve, though the ghostly beating of his drum may still be heard. Another person to starve in the castle is a young who supposedly wanders the corridors.
In the grounds a distressed white lady haunts. Allegedly she had fallen foul of Sir Roger Fiennes (veteran of Agincourt) who abused her then murdered her. It was Sir Roger Fiennes who built the castle in 1441.
