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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
