The name Dùn dà Làmh is Gaelic and means fort of the two hands.[2]
Dùn dà Làmh sits on a hilltop overlooking a dam on the river Spey to the north, and towards the south it has a view of the River Mashie and Strath Mashie.[3] The hillslopes are steep on three sides, with only the west being more accessible.[4]
The approximate size of the fort is 110 metres (360 ft) in length, with width varying between 30 and 75 metres (98 and 246 ft).[4] The fort has ramparts constructed from slabs. The ramparts at the western section are the ones best preserved.[4] On average the ramparts are between 4 and 5 metres (13 and 16 ft) wide, with a maximum of 7.5 metres (25 ft). The interior of the fort is around 4,000 square metres (43,000 sq ft) in size.[3] The interior of the fort is mostly free from trees although sproutlings are appearing.[4] Within the fort there are two shelters, which are believed to have been constructed by the Home Guard during the Second World War.[4][5]
The fort has not been excavated, but was archaeologically surveyed in 2010–2011.[3][4]
