Whilst the Ordnance Survey maps of the area dutifully noted this sacred ground, no archaeological evidence has emerged to confirm its ancient religious significance. The graveyard sits about 75 metres south of the local Church of Ireland, and historical accounts suggest these two burial grounds may once have been connected as a single cemetery. According to local historian Bonner, writing in 1972, the original graveyard stretched from Ardmore across what is now the village road to where the current church stands; road workers widening the thoroughfare reportedly uncovered human bones in the soil, lending credence to this theory.

The Church of Ireland building appears to have been constructed atop an earlier church site, with headstones in its surrounding graveyard dating back to the early 1700s. The grounds extend to the south and west of the church, potentially linking up with Ardmore Graveyard some 60 metres away. Despite the absence of any visible church ruins within Ardmore itself, the site maintains its designation as a place of historical interest, recorded in the Archaeological Survey of County Donegal compiled in 1983.

Archaeological testing carried out in 1999 near the south-east end of Culdaff village revealed little of the area’s ancient past. When archaeologists arrived to conduct pre-development testing for a house extension, they found the foundation trenches had already been dug. The excavations, ranging from 0.9 to 1.4 metres deep, revealed only modern fill and topsoil directly above bedrock, containing 20th-century pottery sherds, bottles, and ashes; evidence that this particular plot had served as a backfilled garden for the previous 60 to 70 years. Whilst this investigation yielded no archaeological discoveries, the broader landscape of Culdaff continues to hold tantalising hints of its early Christian heritage, preserved in place names, local memory, and the weathered stones of Ardmore Graveyard.
