The Staines area seems to have had a prehistoric landscape which is comparable to the one in Wiltshire, with the Negen Stones and the Stanwell cursus even seeming to parallel the Stonehenge arrangement. It is now almost completely eradicated by the modern environment, but luckily the sites were investigated and their positions recorded just in time. And they show that the ancient ley system discovered by Alfred Watkins is indeed a reality.
