The Carn Euny Ancient Village is an ancient village located in southwestern England. This village was initially built during the late Iron Age around 400 BC, and it was occupied until 400 AD. The Carn Euny Ancient Village went through several stages of development. The earliest houses are called roundhouses, and they were made of wood and turf between 500-400 BC. The last houses built in the Carn Euny Village were stone courtyard houses. These houses were larger, made of stone, and contained an oval-shaped courtyard. Besides the houses, the Carn Euny Ancient Village is known for its fogou. Tin miners discovered it in the 1840s, and WC Borlase excavated it in the 1860s. The fogou is an underground tunnel that was lined with rocks. Scholars debate the fogou’s function, with possible theories including a storage unit, a place of refuge, or a religious site to an earth goddess.
