This ancient megalithic structure, situated about 300 metres west of Port Lough amidst furze-grown rocky hills, has been known by various names throughout history; the 1847 OS map labelled it ‘Calluragh Burial Ground’, whilst earlier field maps referred to it as ‘Labby Dermot and Grania’, connecting it to Ireland’s legendary lovers from the Fenian Cycle. The monument sits on a gentle slope with the dramatic backdrop of Croaghaderry ridge to the south and the imposing Muckish Mountain forming the distant skyline.

What remains today is a D-shaped mound rising about a metre high, with its straight side measuring 9.3 metres along a WNW-ESE alignment. Several large stone orthostats protrude from various points of the mound; four are exposed on the eastern side, with the largest leaning outward at 2.2 metres long, whilst two parallel stones jut from the northern section, the taller rising 0.9 metres above the mound’s surface. The southern portion of the monument was unfortunately removed years ago, and Thomas Fagan recorded in the 1840s that stones had been taken from the site for building materials, during which decayed bones were discovered. Archaeological analysis suggests these remains represent some form of megalithic gallery, possibly a wedge tomb, though its unusual north-south orientation makes definitive classification challenging.

The site’s later history as ‘Calluragh Burial Ground’ reveals its use as a cillín, an unconsecrated burial place for unbaptised infants, a practice observed at numerous other megalithic tombs across Ireland. Archaeological testing conducted in 2001 in the surrounding area found nothing of additional significance, though the monument itself remains an intriguing puzzle. The exposed orthostats hint at what might have been an elaborate chambered structure, whether serving as a passage tomb for Bronze Age communities or fulfilling some other ceremonial purpose lost to time, before finding new meaning in more recent centuries as a place of quiet burial for the community’s most vulnerable souls.
