Ballowall Barrow is a prehistoric funerary cairn (chambered tomb) containing several phases of use from the Neolithic to the Bronze Age. It is situated on the cliff top at Ballowall Common, near St Just in Cornwall.
It was first excavated in 1878 by William Copeland Borlase, when it was discovered under mining debris. Reconstruction work which was done after the excavation to make the inside more accessible has further complicated the site. The site today is a confused mix of original and reconstructions introduced by Borlase. The finds from excavations are in stored in museums at Truro, Cambridge and the British Museum.
The construction of the site is unique in consisting of a combination of Neolithic and Bronze Age funerary rituals. A similar site was recorded by Borlase but its location has been lost.
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.
