Local tradition holds that St. Patrick himself founded this religious settlement, which would place its origins in the 5th century. The site centres on a roughly rectangular graveyard that contains several significant medieval features, whilst just outside the western entrance stands a tall, unadorned high cross with a distinctive ring connecting its arms; a style typical of Irish ecclesiastical art.

Within the graveyard walls lie the remains of two churches and what appears to be a mortuary house or tomb shrine. The North Church, which once served as the medieval parish church, has largely vanished save for its eastern gable wall. This surviving section, built from roughly coursed split stone and rubble, rises about 3.7 metres high and features a narrow window with splayed sides, though its jambs have long since disappeared. The wall's construction incorporates two blocks showing the characteristic punched dressing of medieval stonework, now reused in the northwest corner of the graveyard boundary.

Archaeological evidence suggests the current graveyard walls may follow the original footprint of the North Church, with the western boundary possibly marking where the church's west wall once stood. The southern wall has completely disappeared, whilst a table tomb now obscures the southeast corner of the structure. Despite the fragmentary nature of what remains, these ruins offer a tangible connection to centuries of religious life in Donegal, from possible Patrician beginnings through to its role as a medieval parish church.
