Swinside, which is also known as Sunkenkirk and Swineshead, is a stone circle lying beside Swinside Fell, part of Black Combe in southern Cumbria, North West England. One of around 1,300 recorded stone circles in the British Isles and Brittany, it was constructed as a part of a megalithic tradition that lasted from 3300 to 900 BC, during what archaeologists categorise as the Late Neolithic and Early Bronze Ages.
