Auchagallon Stone Circle is the remains of a Neolithic or Bronze Age burial cairn, surrounded by a circle of fifteen stones. The cairn and stone circle is situated on a slight ledge of a west-facing slope, overlooking Machrie Bay. The circle comprises fifteen blocks varying in height from 0.5 metres to 2.3 metres. The stones are of red sandstone, except two which are a pale grey granite. The circle has a maximum diameter of 14.5 metres.
In the centre is a large stone cairn. Antiquarians digging here in the 19th century found a burial cist in the centre, although there are no records of any other remains. Although the monument is now called a stone circle, it was probably built as a kerbed cairn.
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.
