Castle Dore is a small multivallate Iron Age hillfort near Fowey in Cornwall, dating from the 5th-4th century BC to the 1st century BC. Excavated by C.A. Raleigh Radford in 1936-37, the fort encloses 0.5 hectares within concentric circular and oval ramparts. Around twenty roundhouses were uncovered, along with South-Western Decorated pottery, cordoned wares, glass bracelets, and amphorae. Radford claimed evidence of a Dark Age timber hall linked to King Mark of the Tristan legend, though later scholars determined nearly all artifacts predate the Roman period. The site also witnessed a 1644 English Civil War skirmish between Royalist and Parliamentarian forces.
