Round barrows date from the Bronze Age circa 2500 – 1600 BC, and are one of the more common ancient sites. They are typically found on ridges, hills and cliff tops. Some are found alone; others are strung out in lines or clustered in groups. They are marked on maps as ‘tumuli’ and are often found in association with other ancient sites such as stone circles. They vary widely in style and size, but most contain a centrally placed burial, usually cremation, in a pit or stone cist (a small, coffin-like stone box).
