An abbey is said to have been founded here in 580, over which St. Colgan presided. The parish comprises 5128 statute acres, as applotted under the tithe act, and contains some limestone. An inlet of the bay of Galway extends up to it, and is navigable for small boats; large quantities of sea-weed are collected for manure. Tyrone is the seat of A. F. St. George, Esq.
