Lough Ree (Irish: Loch Rí – Lake of the Kings) on the River Shannon, Ireland, separating Counties Longford and Westmeath (east) from County Roscommon (west). The irregular shoreline is varied and includes both deep bays and shallow inlets. There are numerous islands, accessible by boat from Athlone. On several of the larger islands are remains of ancient churches. The lake is noted for its fishing.
The small town of Lanesborough is at the northern end of the lake. This mystical lough studded with islands is a place of great myth and legend. Sprits of high kings, ghosts of fallen warriors, there is even the rumour of a lake monster! The Lough Ree monster!
