Bridge of Dunn broch (Old Hall of Dunn 1)
Perhaps the most notable aspects that identify this as the site of a broch are the typical Caithness 'mound on a mound' appearance and the site being well suited for a broch. Other than that it's just a grass covered mound of rubble. Judging by the size of the mound I'd speculate that there is much underground waiting to be excavated.
I'm not sure what the best route is to the site as I took a circuitous route through an adjacent farm after speaking to the farmer and wandering through fields and negotiating gates. I'm sure there must be an easier route.

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. The information here is provided free but it is your responsibility to ensure its accuracy, ensure your own safety, and acquire permissions for access where necessary.
