Restormel Castle

Restormel Castle (Cornish: Kastel Rostorrmel) lies by the River Fowey near Lostwithiel in Cornwall, England, UK. It is one of the four chief Norman castles of Cornwall, the others being Launceston, Tintagel and Trematon. The castle is notable for its perfectly circular design. Although once a luxurious residence of the Earl of Cornwall, the castle was all but ruined by the 16th century. It was briefly reoccupied and fought over during the English Civil War but was subsequently abandoned. Now in the care of English Heritage, it is open to the public.
