King Arthur's Hall is a megalithic enclosure on Bodmin Moor in Cornwall, England. It is thought to be a late Neolithic or early Bronze Age ceremonial site.
The monument consists of fifty-six stones arranged in a rectangle with a bank of earth around them and measures approximately 20m by 47m. The interior fills with water and a contemporary ground level has not been established. It has suffered damage by cattle in the past and is now protected by a gated fence. It can be reached by footpaths east of St Breward.
The surrounding area contains many stone circles, hut circles, cairns and cists.
In the absence of any archaeological finds, its origin and use is only speculative. A similar enclosure exists in Brittany which was a Bronze Age cremation site, but a similar rampart construction at Lough Gur in Ireland suggests an earlier Neolithic date. It has even been suggested that it was merely a medieval cattle pound, but the effort required to build the bank and to erect the slabs suggests that it had a more important function.
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.
