The largest complete henge in Britain is 640ft (500m) in diameter and encloses a natural valley. It may have been built to 'close off' the area once it fell out of use. This area contained timber circles and what seem to have been shrines. The area outside the ditch and bank (and partly under it) was once a settlement, perhaps containing hundreds of houses, making Durrington Walls potentially the largest village in north-west Europe at the time. People and their livestock travelled from across the country to feast and take part in ceremonies at the midwinter solstice. Woodhenge, nearby, was an impressive timber circle surrounded by a bank and ditch.
