What makes it quietly arresting is not simply the setting but the way the dead have been marked: carved architectural fragments salvaged from the island's own ruined church and priory serve as grave-markers, meaning that the boundaries between the living complex and the burial ground have long since dissolved into one another. Some of the upright stones bear no inscription at all, their original carved decoration from older structures now doing the work of memorialising people whose names are nowhere recorded.

Inchmore Island holds the remains of two medieval religious structures side by side within the same subrectangular enclosure, roughly 61 metres along its longer axis. At the southern end sits a ruined church; at the northern end, the remains of an Augustinian priory. The Augustinians were a mendicant order who established numerous smaller houses across Ireland during the medieval period, often in lakeside or island locations that combined seclusion with accessibility by water. Here, the two buildings and the graveyard between them have effectively merged over time, with stonework from both structures redistributed among the burials. Memorials on the island range in date from the 18th to the 20th centuries, suggesting the site remained in active funerary use long after any religious community had departed.

Access to the graveyard is through a wrought-iron gate and adjoining stile set into the southern end of the western wall. Reaching it in the first place requires crossing to the island, which sits in Lough Gowna on the Longford and Cavan border. The heavy scrub cover means close inspection of the stones takes some patience; many of the reused architectural fragments are partially obscured, and the uninscribed markers can be easy to overlook among the vegetation.
