The Grey Mare is the remains of a neolithic long barrow near Abbotsbury in Dorset. Now a rather disordered heap of stones it dates from around 3000BCE.
The capstone has slipped but it is still an impressive monument even if it is close to a field gate. At least there were no cows although they had left plenty of evidence of their presence!
This was a pleasant stroll from the Kingston Russell Stone circle although it was further than we expected and a lot of peering through bushes occured in case we were walking past it on the wrong side of the hedge!. Once we were close enough though it was hard to miss.
