Read about the story of the Horseshoe Enclosure here
The site chosen for the construction of the Neolithic Horseshoe Enclosure had a long history of human activity. Flints and pottery from this monument indicate that it was used between 3300 and 2000 BC. It lies within a small linear cursus on a ridge above the Stanwell Cursus. The enclosure was formed by two curved ditches with internal banks and had two opposing entrances. One entrance faced the Stanwell Cursus and the other a small ring ditch. In the flat landscape the banks would have been visible from some distance through cleared avenues in the woodland. But the Horseshoe Enclosure was designed to separate this small, special space from the world of everyday life rather than to make an impressive visual statement. It would have held about a dozen people, perhaps priests celebrating sacred rites, while the rest of the community congregated outside. The sight-lines out of the monument indicate that the ceremonies may have been associated with the mid winter and mid summer solstices.
