Castle-an-Dinas is one of the largest hillforts in Cornwall with a diameter of around 850 metres, situated on a hill 700 metres above sea level. It dates from the Iron Age, around 200-300 BC, when the ramparts would have been higher than today and probably topped with a wooden palisade. Inside the ramparts would have been wooden buildings, of which no trace now remains. The marshy area could have once been a well, providing water for the settlement. Also within the central area are two Bronze-Age barrows which indicate the hill was in use before the ramparts were built during the Iron Age.
