The Watchstone

1760 Pococke’s drawing shows a second stone on the opposite side of the road a little further away from the roadside. This is longer than it is tall and resembles a recumbent [though I suppose it could be a very large natural boulder like the Savile Stone]. The ‘companion’ stone is actually a diamond shape which if to the same scale as the Watch Stone would come oot as some 14’ high and wide ! As far as I can tell from Pococke’s drawing it would have been about grid ref HY30671275.
Wilson 1842 “Close to either side of the southern end of the bridge... stands a great sentinel stone...
...as you approach [the Ring of Brodgar] you pass here and there a solitary stone or broken remnant, as if there had been... a connecting range or approach, all the way from the bridge to the great circle”
