The Callanish VIII stone setting is one of many megalithic structures around the better-known (and larger) Callanish Stones (I) on the west coast of the isle of Lewis. This is a very unusual (and possibly unique) setting, with a semicircle of four large stones on the edge of a cliff on the south of the island of Great Bernera and looking across a narrow strait to Lewis. There is no evidence that the cliff has collapsed here and destroyed half of a complete circle - it would appear that a semicircle was the original intention. The tallest stone is nearly three metres high and the cliff-edge axis of the circle gives a diameter of about 20 metres.
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.
