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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
