DISERT, or CARRIGEEN, a parish, in the barony of COSHMA, county of LIMERICK, and province of MUNSTER, 1 ½ mile (W.) from Croom; containing 180 inhabitants. The church having long since fallen to ruin, the parishioners attend divine service at Croom. On the north side of the ruined church is a remarkable round tower, about 70 feet in height, standing on a rock of limestone: 14 feet from the foundation a circular-headed door opens to the north-east; on the opposite side is a pointed window, over which are three stories with square-headed lights, and at the top are four small slip windows. The mouldings round the door are in relief, and of superior workmanship in freestone, of which the window-frames are also composed; the remainder of the tower is constructed of limestone.
