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.
Access is the same as for the Cairn of Dunn broch. There is a parking layby where the telephone is indicated on the map, but no telephone, and the layby is clearly marked with sign posts. It's a hundred yards or so along the main road from there to the track leading up to the farm. It's a fast road though and narrow, so use the road when there are no cars and step up onto the grassy verge and wait for them to pass when there are cars approaching. It's a fast straight road so beware of overtaking vehicles. At the top of the track there are easy gates to climb or open to access the Cairn of Dunn broch and then further down the field more easy gates to access the Bridge of Dunn 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. 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. Accessing brochs is done entirely at your own risk.
