Chûn Quoit is one of the best preserved of all Neolithic quoits (also called dolmens or cromlechs) in western Cornwall. Like the other quoits, it was probably covered by a round barrow, of which much evidence abounds. It was a closed chamber and its mushroom-domed capstone measures 3.3 m by 3m. There is a cup mark on top of the capstone. It is supported about 2 m from the ground by four substantial slabs. There is evidence of an entrance passage to the south-east within the mound area. The site was examined in 1871 but no significant finds were made.
In the vicinity of Chûn Quoit there are many other megalithic and archaeological sites, such as Lanyon Quoit, Mulfra Quoit, Mên-an-Tol and Mên Scryfa. The rocky outline of Carn Kenidjack marks the position of midwinter sunset away to the south-west.
This is the only dolmen in West Penwith to retain its capstone 'in situ' – others have been re-settled. It is believed to have been built around 2400 BC, two millennia before the neighbouring Chûn Castle.
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.
