In Kilgalligan graveyard which is close to the beach at Broadhaven Bay there is a large mound about which there are many stories. It has never been archaeologically investigated. It may be the remains of the early Christian church of St. Galligan, from who this townland takes its name. Galligan himself is considered to have been buried within the large cairn. Nearby is a holy well to which people come on pilgrimage on 14 August, the Eve of St. Galligan's Feast.(Corduff, Irish Folklore Commission). In the 1830s a survey reported that "the cairn was caused by accumulated burials until a sort of pyramid has been formed that, at a distance, has a curious effect with the headstones and small crosses covering all sides of its conical surface. Another writer at the time described it as "here are the ruins of a monastery".(Samuel Lewis, Topographical Dictionary)
