Belas Knap Long Barrow
Other examples, such as Uley and Nympsfield barrows, have strongly emphasised entrances with chambers opening out on either side of a central passage.
It is a type of monument known as the Cotswold Severn Cairn. Construction is estimated to have taken place around 3000 BC, with following successive burials over a period of years and then the burial chambers were deliberately blocked.
