Restormel Castle lies by the River Fowey near Lostwithiel in Cornwall. 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. It is an unusually well-preserved example of a circular shell keep, a rare type of fortification built during a short period in the 12th and early 13th centuries.
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. It is now in the care of English Heritage and open to the public.
Today the castle commands fantastic views across the valley of the river Fowey and is a favourite picnic spot – with beautiful spring flowers, and plants all year round.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
