Wiltshire's chalk downland is home to one of the densest concentrations of prehistoric burial monuments in Europe. The Neolithic long barrows, dating from approximately 3800 to 3400 BC, are among the oldest surviving structures in Britain — communal tombs built of earth, chalk, and stone where the remains of the dead were deposited over centuries. The later round barrows of the Bronze Age, dating from around 2400 to 1500 BC, mark a shift to individual burial, often accompanied by rich grave goods.
The long barrows are monumental in scale: West Kennet, the largest in this guide, is over 100 metres long. They were not simply graves but places of ongoing ritual — bones were rearranged, chambers reopened, and offerings made over many generations. The round barrows cluster in cemeteries on ridgelines and hilltops, positioned to be seen from a distance, marking the landscape with the presence of the honoured dead.
This guide covers six exceptional sites, from the accessible and well-interpreted West Kennet to the more remote Adam's Grave on the chalk scarp above the Vale of Pewsey. Each entry includes grid references, directions, and notes on what to look for. Several sites are within easy reach of Avebury and Stonehenge, making them natural additions to a day exploring either monument complex.
A note on access: all sites in this guide are on open land or public footpaths, but please respect the monuments. Do not climb on barrows, disturb loose stones, or leave offerings that will litter the site. These are ancient and fragile structures.
