Limerick is an inland county of western Ireland in Munster Province, bounded on the north by the River Shannon estuary and County Clare, on the east by County Tipperary, on the south by Cork, and on the west by Kerry. Its area is 1064 square miles.
The surface of Limerick is generally level with a few low ridges such as the Galtee Mountains in the southeast, the Slieve Felim Hills in the northeast, and the Mullaghareik Hills in the southwest. The county has several rivers in addition to the Shannon and one small lake, Lough Gur, in the eastern part of the province near Herbertstown. Around Lough Gur are cromlechs, menhirs, stone circles, pillars, altars, and a massive square stone tower. At Adare is an ancient 14-arched stone bridge over the Maigue River. Limerick is the chief town.
