Ballamooar is thought to be the site of a keeill or chapel, which would have been in use from circa AD500 until circa AD1000. The old farmhouse stood in an enclosure known as Faie Cabb'lagh, the Chapel Close, which stands some 20 metres above sea level. The keeill was close to the gable of the house but has long since been destroyed and no trace of it now remains.
