Carn Euny

Carn Euny is an archaeological site near Sancreed, on the Penwith peninsula in Cornwall [1]. It consists of evidence of both Iron Age and post-Iron Age settlement, with excavation on the site showing activity at Carn Euny as early as the Neolithic period [1]. The first timber huts there were built about 500 BC, and 400–500 years later were replaced by stone huts, the remains of which are still visible [1]. Carn Euny is best known for the well-preserved state of the large fogou, an underground passageway, which is more than 65 feet long [1]. This fogou runs just below the surface of the ground and is roofed with massive stone slabs [1]. The site was abandoned late in the Roman period [1].
