Treryn Dinas

Treryn Dinas is a clifftop fort dating from the Iron Age. It consists of a huge outer earth bank which is several metres high in places. Inside this is a large flat area that once might have been settled. Beyond this are a series of banks and ditches before the narrowest point in the headland, where there is a final ditch and stone-fronted rampart. The reason for the inner ramparts is not well understood. It could have been a more fortified position to retreat to if the outer defences had been breached, but the inhospitable rock outcrop would not have been somewhere that a siege could have been withstood for long. Some historians have suggested that the smaller ramparts around the inner area could have been non-military, for example to separate off a ceremonial area from "the rabble".
