We visited this site 2 years ago. It occurred to me that this may have been a very important place, given it’s situation in the Earn Valley.
Dundurn, just up the valley, was an important place 2000 years ago, certainly, and probably was for a long time before. This place was apparently at the border of the pictish and celtic kingdoms and has no doubt marked a boundary between the rugged highland westlands, and the fertile farmlands on the east since the neolithic.
This site is marked on the map as a former circle and now just the 2 stones remain.
