Lough Erne
Lough Erne is an extensive lake system in the southwest of Northern Ireland, primarily located within County Fermanagh. It consists of two main parts, Upper Lough Erne and Lower Lough Erne, which are linked by the River Erne. Lower Lough Erne is the larger section and is known for its wide expanses of water, while Upper Lough Erne is characterised by a labyrinth of numerous islands and channels. Historically, the lake was a vital defensive line and a religious centre, evidenced by the medieval monastic ruins on Devenish Island. During the Second World War, the lake served as a crucial base for Royal Air Force flying boats conducting patrols over the Atlantic. The town of Enniskillen is strategically situated on an island between the two lake sections. Today, Lough Erne is a premier destination for water sports, angling, and nature enthusiasts. The Erne-Shannon Waterway further connects the system to the River Shannon in the south.
