Halliggye Fogou, Iron Age underground passage in Trelowarren Estate, Cornwall, Great Britain
The underground complex features a main passage extending 20 meters north-south, connecting to a curved tunnel stretching 28 meters to a small chamber.
The structure dates from 500 BC and remained active until the 2nd century AD, with pottery finds indicating continuous occupation for approximately 700 years.
The term fogou originates from the Cornish word ogo, meaning cave, representing a type of underground structure found exclusively in western Cornwall.
Visitors can access the fogou from May to September, while winter closure protects hibernating horseshoe bats that inhabit the underground passages.
During World War II, the Manaccan Auxiliary Unit utilized this ancient underground structure to store explosives and ammunition for military operations.
