Foyle Port is a port located on Lough Foyle in Northern Ireland. It is the United Kingdom’s most westerly port and an important northerly port on the island of Ireland.[1] The current port is at Lisahally, County Londonderry, though historically the port was upriver in the city of Derry itself. It is operated by the Londonderry Port and Harbour Commissioners, whose former offices, just north of the city's walls, are now a museum.
