a town of Ireland, in the county of Galway and province of Connaught, is 74 miles from Dublin. The castle of Portumna, the seat of the earl of Clanricarde, is at this place, and near it are the ruins of an ancient castle. There is also a garrison for a troop of horse and two companies of foot. The town is seated on the river Shannon, where it falls into Lough Derg. The monks of the Cistercian abbey of Dunbrody, in the county of Wexford, had for a long time a chapel here, dedicated to St Peter and St Paul; but having at length forsaken it, O'Madden, dynast of the country, gave it to the Dominican friars, who, with the approbation of the monks of Dunbrody, erected a friary here and a church, which they dedicated to the blessed Virgin and the original patron saints; at the same time they built a steeple, and all other necessary offices. Pope Martin V. granted a bull to confirm their possessions, dated 8th October 1426; and on the 23rd of November following he granted indulgencies to all who had contributed to the building. The walls are still nearly entire, and show that the monastery of Portumna was by no means an ignoble structure. The ancient choir is now the parish church.
