Two sketch plans of Dun-Torcuil [Dùn Thorcuill/Dun Torcuill, Uibhist a Tuath/North Uist], the first noting the dimensions of the walls including any difference between the sizes at the bottom or the top of the wall, and the location of the passageway. The circular shape of the dun has been marked into four sections and measured according to those areas. The second has also been marked in this way but contains many fewer measurements.
