EHG5314 - Topographic and photogrammetric surveys - Cam Ma Mairg Broch

Detailed topographic and photogrammetric surveys were carried out by Headland Archaeology in 2018 of Cam Ma Mairg broch, also referred to as Cairn Merk. The surveys of the broch were part of the requirements of the planning condition for the Achlaclan Wind Farm, Caithness. The broch is built on a slightly elevated platform on the east bank of the river Thurso and is enclosed by a ditch that runs into the river at both ends. It has an outer courtyard that appears to run around the entire broch and an external passage leading up to the entrance to the south-east. The surveyed profile indicates that the walls survive to a height of some 4m above the original ground surface. <1>
