TRABOLGAN, a ploughland in the parish of AGHADA, barony of IMOKILLY, county of CORK, and province of MUNSTER, 6½ miles (S. W.) from Cloyne, on the eastern side of the entrance of Cork harbour: the population is returned with the parish. It comprises 842 statute acres as applotted under the tithe act. Here is an extensive and valuable slate quarry, employing a great number of workmen, whence slate of durable quality and excellent colour is procured. Roche's Tower light-house is within this ploughland, as is also the coast-guard station. The whole is the property of E. Roche, Esq., who has here an elegant house and demesne, noticed more particularly in the article on CORKBEG. It is ecclesiastically known as a particle, forming part of the mensal of the Bishop of Cork, to whom the tithes, amounting to £148. 1. 8. are payable: the cure of souls devolves upon the rector of Corkbeg.
