Digital aerial survey of the prehistoric settlement at Mullaghfarna, Bricklieve Mountains, Co. Sligo.
The exposed limestone plateau of Mullaghfarna with its large cluster of circular enclosures has been one of the most enigmatic sites in Irish prehistoric archaeology ever since it was first recorded by Macalister in 1911.
The site, which measures c. 200 x 300 m, consists of some 150 stone built enclosures/hut sites situated directly on the karst limestone pavement
As part of an ongoing research project an aerial survey of the plateau was undertaken using digital photogrammetry. The main aim with the survey was to create a plan of the entire area, where individual stones in each enclosure/hut site could be identified, and thereby enable a detailed interpretation of each site. Another important aim with the survey was to create a base for detailed 3D modelling of each site, but also to model them into their wider landscape context.
The complexity as well as the sheer number of enclosures/hut sites made a traditional survey by Totalstation or GPS impractical.
The paper presents the results from the survey and their archaeological implications.
