European route E1 is a series of roads in Europe, part of the United Nations International E-road network, running from Larne, Northern Ireland to Seville, Spain. There is a sea crossing between Rosslare Harbour, in Ireland, and Ferrol, but no ferry service. The road also passes through Portugal – past the city of Porto, through the capital, Lisbon, and then south to the Algarve, passing Faro before reaching the Spanish border west of Huelva.
