Both the Comet and Watch stone are located between the Ring of Brodgar and Stones of Stenness. It looks as though all the stones are part of the same extended monument, but apparently they were erected over a period of over 1,000 years.

The Comet (shown first) is relatively small – not even my height. The Watch stone is massive!

I like the fact that, although quite a lot is known about these stones and credible theories have been proposed, nobody knows for certain precisely why they were built, or how they were used.

The weather was a bit blurgh when we arrived, stayed that way as we drank a pot of tea and ate Empire biscuits and fruit slices respectively, and stayed that way after we’d had a good look and another tea break, so we plan to go back again later. It would be great to get sunset or sunrise photos, wouldn’t it?
