Bowl barrows were created from the Neolithic through to the Bronze Age in Great Britain. A bowl barrow is an approximately hemispherical mound covering one or more Inhumations or cremations. Where the mound is composed entirely of stone, rather than earth, the term cairn replaces the word barrow. The mound may be simply a mass of earth or stone, or it may be structured by concentric rings of posts, low stone walls, or upright stone slabs. In addition, the mound may have a kerb of stones or wooden posts.
Barrows were usually built in isolation in various situations on plains, valleys and hill slopes, although the most popular sites were those on hilltop. Bowl barrows were first identified in Great Britain by John Thurnam (1810–73), an English psychiatrist, archaeologist, and ethnologist.

The bowl barrow at Wyck Beacon survives well and will contain archaeological information and environmental evidence relating to the monument and the landscape in which it was constructed.
The monument includes a bowl barrow lying on level ground on the crest of a hill in the Cotswolds. The barrow has a mound which measures 24m in diameter, and is about 2.5m high. Although no longer visible at ground level, a ditch, from which material was quarried during the barrow’s construction, will surround the mound, surviving as a buried feature about 2m wide. Excluded from the scheduling is an Ordnance Survey Trigonometry Point which stands on the northern side of the mound, although the ground beneath it is included.
