Catslerigg with its 38 megaliths situated on grassy land near Keswick is older (5 000 years old) than the legendary Stonehenge. Its use, like that of Stonehenge, remains a mystery. The site is all the more remarkable in that it offers a view extending far out towards Thirlmere and Helvellyn to the south and Derwentwater and Keswick to the west.
