Guidebook: Chysauster and Carn Euny

Chysauster and Carn Euny in the West Penwith area of Cornwall comprise groups of stone-walled homesteads of the Iron Age/Romano-Cornish eras. Each house had an open central courtyard surrounded by a number of rooms roofed with turf or thatch. A feature of both villages was an underground walled passage known as a fogou, which may have been a store, a refuge, or even a religious cult centre.
