Roofed and walled in stone, this complex of passages is the largest and best-preserved of several mysterious underground tunnels associated with Cornish Iron Age settlements.
The purpose of such 'fogous' - a Cornish-language word meaning 'cave' - is unknown. Refuges, storage chambers or ritual shrines have all been suggested.
Managed by The Trelowarren Estate. Free entry to the fogou. Entry to the rest of the estate is charged.
Please note: Dogs on leads are welcome. Parking is available and free to members. Visitors are strongly advised to bring a torch.
