Burroughston Broch is an Iron Age structure located on the island of Shapinsay. Excavated in the mid 19th century, Burroughston Broch is still well-preserved. The drystone walls are up to four metres thick in some parts and there is a complete chamber intact off the entrance passage. Some remains of stone fittings are evident in the interior.
The walls of Burroughston Broch have an external diameter of around 18 metres, and an internal diameter of around 10 metres. From the outside, the building appears as a grassy mound, and little of the outer wall is exposed.
The entrance passage is on the east side, and is about 4 metres long, 1.2 metres wide and 1.8 metres high. There is an elongated guard room opening from the left side of the passage. Inside the broch, the outer face of the upper gallery is still visible, and traces of an opening to the upper gallery are still apparent. A deep well is present in the broch floor: the upper part being dry stone masonry, the lower being cut into the rock.
In the sloping area in front of the broch entrance are traces of 'out-buildings' now covered with turf. A wall, ditch and rampart, which probably once encircled the broch, are still evident around the structure.
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.
