Another grassy mound, and a rather small one, but there are a few orginal stones of what I believe is the external wall showing through the ground. It's on the small side, and one or two think it is perhaps a little too small for a broch. I'm of the mind that brochs didn't all have the same purpose and were built to different sizes to serve differing purposes. Some brochs are huge defensive fortresses with outer defence walls and ditches, others are small as they were probably only built to maintain line of sight communications. This one is in line of sight with Thrumpster Little, Cairn of Humpster, Hempriggs. and Tannach Mains as well as the Cairn Hill broch further inland. If I'm right, then its purpose was purely line of sight communications and that accounts for its small size. To understand brochs, you just need a military head and to be able to think strategically.
I parked on a verge nearby at Tannach, walked down the track and cut across the field to the broch.

Disclaimer: Some brochs were built with military defensive purpose, and as such can be situated in extremely dangerous areas, such as on the edge of cliffs and ravines. Additionally, these are Iron Age structures, most of them in ruins, and they are extremely hazardous, with crumbling stone walls and hidden chambers. Existing walls, lintels, and passages could collapse at any time.
