A five-thousand-year-old passage tomb close to the summit of Slieve Gullion near the Hag’s Lake in County Armagh. This is claimed to be the highest such tomb on the island of Ireland.
Archaeological work carried out in the tomb has revealed cremated bone, flint and chert flakes, and a barded and tanged arrowhead.
Leading from the entrance is a lintelled passage which opens out into a corbelled octagonal chamber. On the wall directly opposite the entrance is a small, recessed chamber.
The tomb is aligned so that the setting sun at the winter solstice full illuminates the chamber and the recess beyond.
