The Callanish III stone circle is one of many megalithic structures around the better-known (and larger) Callanis Stones (I) on the west coast of the isle of Lewis. The stone circle consists of two concentric ellipses. The outer ring measures about 13.7 by 13.1 metres. It contains 13 stones, of which eight are still standing and five have fallen. The inner ring is a pronounced oval measuring 10.5 by 6.6 metres. Only four stones remain in the inner circle, the tallest of which measures 2.1 metres. There is no sign of a central mound or cairn.
It is just a few hundred metres from the Callanish II stone circle.
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.
