Carn Ban is a Neolithic chambered tomb located on the Isle of Arran. It is considered as one of the most famous of the Neolithic long cairns of south-west Scotland. It is of a type found across south-west Scotland known as a Clyde cairn. It is trapezoidal in shape, with a semicircular forecourt at the upper northeast end. The forecourt has an entrance leading into a long chamber divided into compartments by cross-slabs, similar to the arrangement at Torrylin Cairn, about 3 miles to the southwest. The chamber of Carn Ban is 30 metres long and 18 metres broad. The tomb was excavated in the late 19th century, but the only finds were a flint flake, an unburnt fragment of human bone, and a pitchstone flake.
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.
