Carn Euny is an Iron Age and post-Iron Age settlement on the Penwith peninsula in Cornwall, England, with archaeological evidence showing activity as early as the Neolithic period. The first timber huts were built around 500 BC, and approximately 400–500 years later these were replaced by stone-walled houses, whose ruins remain visible today.
