This stone is not easy to find as a field hedge has been planted around it. Just off the busy Swindon to Highworth road past the turning for the Honda car factory. The village of Stanton Fitzwarren is situated behind Stanton Park - as you go into the village (by foot) follow the footpath sign to Sevenhampton.
A single sarsen standing stone on the edge of a field, possibly an ancient boundary marker, it stands 5'4" high.
