"Teroy-Almost certainly a Broch" R W Feachem 1963 (Canmore).
Well it sure looks like it might have been a broch, although now much reduced. If you remove the surrounding forestry in the minds eye, Broch or galleried dun, Teroy fort must have been a commanding structure sat on its prominence over-looking the loch. There remains what could be an entrance with a possible intramural guard cell on the ENE side; a ditch of significant depth also protects this area with a steep slope protecting the opposite side. It is a bit tricky finding the place but is possible with a good map and for the broch obsessed, a must.
