I've beento Minchinhampton a couple of times. The first time it took me ages to find, and despite knowing its wherabouts stil managed to drive past 3 times on the 2nd visit, I think its due to the stones being ' on edge' when viewed from the road and virtually invisible.

Also well worth visiting in the local area is the homemade icecream shop on the common, not exactly on topic, but well worth stopping off. Beware of the cows.
