I was actually trying to get to the Giant's Grave further down the road and turned off far too early. Another car pulled up shortly after me and a guy got out and put on walking boots which further confused me. After twenty minutes walking along the valley bottom I realised my mistake, but as it turned out there was something to see after all. Shipley Bottom (or Shapely Bottom as I like to refer to it) doesn't have a huge amount to offer archaeologically, but it does do 'serene', which is not surprising considering its proximity to the Ridgeway path less than half a mile to the west and Liddington Castle a mile to the north. There are two or possibly three barrows along the valley bottom, the western one being the more impressive and better preserved. The eastern one(s) are almost flattened or ploughed out, difficult to say as they just looked like a patch of weeds, but at least that shows that somebody made the decision to stop degrading them.
