Okehampton Castle, a motte and bailey castle, is the largest castle in Devon and the ruins which stand today are situated near the northern edge of Dartmoor.
The castle dates from the late 11th century having Norman origins and is mentioned in the Domesday Book (completed in 1086 AD) which states that at that time it was in the possession of Baldwin de Brionne, the Sheriff of Devon.
Most of the surviving structure, including the bulk of the keep and the curtain walls, is of 14th century construction. It was abandoned in 1539 AD when its owner at that time the Marquis of Exeter was found guilty of treason and executed by Henry VIII.
Apart from the aforementioned story, there have been many other strange reported occurrences at the castle including a visitor who photographed a strange ghostly shape at a window at the top of the keep and also numerous sightings of a ghostly black dog.
