Bosigran Castle Promontory Fort
Cornish promontory forts, commonly known in Cornwall as cliff castles, are coastal equivalents of the hill forts and Cornish “rounds” found on Cornish hilltops and slopes. Similar coastal forts are found on the north–west European seaboard, in Normandy, Brittany and around the coastlines of the British Isles, especially in Wales, Scotland and Ireland. Bosigran Castle is a very simple Iron Age cliff castle positioned on a rocky headland overlooking very steep granite cliffs. The castle mainly consists of a wall, around a hundred meters long, that was built across the headland, as if to enclose it.
