Maen Castle is an Iron Age promontory fort or cliff castle located close to Land's End in Cornwall, dating back over 2,500 years to approximately 500 BC. The site features a stone rampart, ditch and counterscarp bank built across a headland neck with nearly sheer cliffs on two sides, representing one of only two fortified sites in Cornwall where Early Iron Age pottery has been found. Excavations in the late 1930s and 1940s uncovered approximately 300 pottery sherds spanning 400 BC to 400 AD, and the site underwent partial restoration in the 1990s to highlight the stone entrance and defensive structures. Now managed by the National Trust and situated near Sennen harbour, Maen Castle stands as the westernmost of all fortified sites in mainland England.
