Cross, Carn, Pettigo, Co. Donegal
Where once a substantial church stood, measuring 66 feet by 22 feet according to 19th-century historian O’Connor, nothing now remains above ground. The site appears on the second edition Ordnance Survey 6-inch map marked as a ‘church in ruins’, but even that description proves optimistic; today, only grass-grown mounds in the surrounding graveyard hint at the ecclesiastical structures that once occupied this spot.
The church, believed to have been erected towards the latter part of the 15th century, has left behind one significant artefact: a ringed cross standing 0.76 metres high with a diameter of 0.27 metres. This ancient Celtic cross wasn’t originally from the site; O’Connor identified it as having been transferred from Saints Island in Lough Derg, the famous pilgrimage lake that lies just across the border in County Donegal. The connection to Lough Derg runs deeper than this relocated monument, as an ancient roadway used by pilgrims travelling to the holy sites at the lake passes directly by the church ruins.
The site offers a tangible link to Ireland’s medieval pilgrimage traditions, when journeys to sacred places like Lough Derg formed an essential part of religious life. Though the church itself has vanished, the combination of the imported cross, the old graveyard mounds, and the pilgrims’ road creates a palimpsest of religious history stretching back over five centuries. The Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, captured these details before even more of the site’s physical traces could disappear into the Donegal landscape.
