The Sanctuary and West Kennet Avenue
Overton Hill, near Avebury, Wiltshire, England, United Kingdom
A late Neolithic concentric complex of stones and posts on Overton Hill, excavated in 1930 and marked today with painted concrete blocks, standing at the end of the West Kennet Avenue that runs to the Avebury henge.
The Sanctuary is the Avebury landscape's strangest ruin to look at and one of its most interesting to read. What survives above ground is Cunnington's 1930 interpretation made physical: blue rectangular blocks where sarsens once stood, red circular blocks where posts did, ring after concentric ring shrinking to a center of six small posts, the outermost circle 40 metres across with 42 stones. Built around 2500 BC, it was a ceremonial structure where movement itself was the ritual: finds of bones, tools, and pottery appear placed according to patterns as people moved through the rings, and the architecture controlled who could see what. Mike Pitts's 1999 dig showed the posts were repeatedly replaced, and English Heritage now presents the monument as probably free-standing rather than roofed. John Aubrey named it in 1649, William Stukeley drew it in 1723, and farmers destroyed it shortly after, making it one of the best-documented losses in British archaeology.
The Avenue is the reason to walk here: the West Kennet Avenue runs about a mile and a half from the Avebury henge to the Sanctuary, a paired-stone processional way that turns the whole distance between the two monuments into a single ritual route, walked today by visitors, solstice crowds, and the modern Druid and pagan communities who treat the Avebury landscape as a living ceremonial site. The library already carries the Avebury henge and West Kennet Long Barrow; this entry belongs to that family as the southern anchor of the complex, and it sits inside the 1986 World Heritage listing. The honest frame is that the Sanctuary's rings are an archaeologist's sketch of a lost building, visited through interpretation rather than presence, and that this is precisely what makes it instructive: you walk the Avenue and arrive at a structure made of evidence.
