Cruach Sleibhe Dun
On the level summit of a rocky outcrop on the east face of Cruach Sleibhe, about 550m north of Calgary Farmhouse, there are the wasted remains of a stone-walled enclosure which may have been a dun. It is surrounded on the south east by a steep rock face and on the north west by boggy ground.
It is oval in shape, but the single wall has been heavily robbed leaving only a scattering of grass-covered debris surrounding all but the south east side of the summit of the outcrop. The internal enclosure measures 14 m by 9.5 m. The position of the entrance is unclear.
A relatively-recent, ruinous stone wall crosses the enclosure and a recent boundary wall has been built on top of the enclosure wall on the north side.
