This ancient cemetery forms a modest rectangle, roughly 25 metres east to west and 15 metres north to south, with three sides defined by stone walls whilst the fourth dramatically drops away to the cliff edge below. The site’s exposed location would have offered medieval mourners sweeping views across the lough, perhaps providing some solace as they laid their loved ones to rest.

At the heart of the graveyard stands what locals have long called a ‘church’, though its true nature remains debatable. Three drystone walls, each about a metre wide and slightly less in height, form a small rectangular structure measuring just 4 by 5 metres internally, with its western end left open. Within this enigmatic building’s northeastern corner sits a low rubble cairn known locally as an ‘altar’, which archaeological evidence suggests may actually be a leacht; a type of outdoor altar or commemorative monument common in early Irish Christianity. This rectangular stone feature, defined by orthostats set on edge and originally roofed with capstones (only one remains in place), bears a striking resemblance to similar structures found at Ollamurray on Inishmurray island in County Sligo.

The site’s most intriguing features include a pillar stone standing 85 centimetres tall on the western edge of the leacht, its west face bearing a hollowed Latin cross that appears sunken into the stone’s surface. A quern stone once rested atop the leacht but has since found a new home in Greencastle’s maritime museum. Near the western entrance, visitors can spot a small stone cross still supported by half of its original socket stone. The graveyard contains numerous grave markers, and according to the landowner, a second decorated slab featuring scrollwork once stood north of the possible church before disappearing in recent times, its current whereabouts unknown.
