Your enthusiasm seems about right, Castlerigg must be among the most spectacular prehistoric sites in this country and there cannot be very many comparable places anywhere. Been around ages too, some say 5,200 years or thereabouts. There is a mystery about the rectangle of stones toward the east side of the ring with no one seeming to have much idea what it might represent. First time I went there we arrived just as rain was easing off. Getting out of the car I saw a fine rainbow pointing (from where I stood) over the wall into the field where the circle dwells. Talk about a welcoming party. Did you stay at the nearby campsite? It's a great way to experience both sunset and dawn among the stones. Dyer ("The Penguin Guide to Historical England and Wales", London, 1981, p.84) points out that virtually all of the stones remain in their original position. This plus the entirely natural effects of more than fifty centuries of Cumbrian weather give grandeur to a place of pure magic. And the sunsets, the sunsets... Surely Castlerigg was known far and wide. Treeman
