Simple kind of round barrow found widely over northwestern Europe from the Neolithic onwards, although especially common in the late 3rd and early 2nd millennia bc. Bowl barrows are distinguished by having a roughly hemispherical mound of turf, earth, and deposited bedrock over a centrally placed primary burial, either in a pit or in some kind of stone or wooden cist. Satellite and secondary burials are common within the mound. Bowl barrows are typically between 3 m and 40 m in diameter and anything up to 6 m high. Some are edged with stone kerbs, and a few examples had concentric rings of posts within the barrow mound as a constructional device. Many have surrounding ditches that provided a quarry for the mound‐building material. Excavation often reveals that these monuments were constructed and enlarged over a considerable period of time. Certainly they were conspicuous features of the landscape for millennia, and in some cases remain so.
