Penstowe Castle, also called Kilkhampton Castle, was a medieval fortification built near Kilkhampton, Cornwall, possibly during the years of the civil war in the 12th century known as the Anarchy.
The precise date of Penstowe Castle's construction is uncertain, but it was built during the years of the Anarchy in the mid-12th century, either by Robert, 1st Earl of Gloucester, feudal baron of Gloucester, who was certainly the tenant-in-chief of the manor of Kilkhampton, or by his tenants and relatives the Grenville family (possibly Sir Richard I de Grenville (d.post 1142) of Neath Castle, Glamorgan), which held the manor of Kilkhampton and the manor of Bideford in Devon from the Honour of Gloucester. Stowe House was the Grenvilles' residence at Kilkhampton, demolished and rebuilt in grand form in 1679 by John Granville, 1st Earl of Bath (1628-1701).
Kilkhampton Castle was built to a motte and bailey design, positioned on a knoll and protected by steep slopes on the north and south sides. The motte today is shaped as an oval, 18 metres by 8 metres. The configuration of baileys is unusual, although similar to nearby Eastleigh Berries Castle. A D-shaped building was located on top of the motte.
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.
