Caisteal Na Coille Broch (Castle Cole)
This broch commands an unassailable position on a heavily fortified hilltop perched over a deep ravine into the Black Water, a tributary of the River Brora. That this was built with military purpose has to be beyond dispute. One can only imagine the fear these brochs and the painted Picts who built them must have put in the hearts of the Romans. This is a much smaller broch than any I've encountered before, so brochs were obviously not built randomly, but to specific blueprints that would accommodate specific numbers of people.
You can park at Balnacoil and walk up the land rover track (marked on the map). There is deer stalking with high powered rifles on this estate, so it might be wise to contact the estate before venturing up 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.
