There are quite a few stone circles all over the British Isles. None of them is a well know as Stonehenge, I think mainly because none of them is a well developed as Stonehenge. However there is quite a nice circle at a place called Avebury that is quite close to Stonehenge. The stones in the circle are more rough but in a way it is more interesting, because at Stonehenge you can only walk along a specially prepared path that does not go close to the monument, whereas in Avebury you can go right up to the stones.
