Foyle Port, otherwise known as Londonderry Port, is a port at Lisahally in County Londonderry, Northern Ireland. The United Kingdom’s most westerly and Ireland's most northerly port, Lisahally Terminal has 440 metres (1,440 ft) of quay and can facilitate vessels up to 62,000 GRT. Primarily a bulk port and major importer of oil, coal, animal feed, fertiliser and plywood the port also accepts cruise ships at the city centre berths, at its commercial port at Lisahally as well as the tender port of Greencastle. The current port is on the east bank of the River Foyle at the southern end of Lough Foyle, by the small village of Strathfoyle, about 5 miles (8.0 km) north-east of Derry. It is operated by the Londonderry Port and Harbour Commissioners, whose former offices, just north of the city's walls, are now a museum.
Most of the current Londonderry Port is in the townland of Lisahally (or Lissahawley), a toponym that may be derived from Irish Lios a' Chalaidh, meaning 'ringfort of the landing place'. Known as Lunnonderrie Hairbour in Ulster-Scots, the port has witnessed mass emigration of Irish and Scots-Irish people over the centuries to North America, Scotland, England and Australia.
The port had a thriving shipbuilding business and was known for building clipper ships. Shipbuilding at the port declined after the introduction of iron vessels, and no large ships were built for some decades after 1846. The Foyle Shipyard, founded in 1882, brought shipbuilding back to the port, but it ceased trading in 1892.
The port saw the transport of many goods over the centuries. Seed potatoes were shipped to places as far away as Egypt. Cattle were regularly shipped to and from Glasgow by the Burns and Laird steamer until the late 1960s. Manufactured items including linen, linoleum and shirts were exported to Great Britain for onward distribution. The McCorkell Line sailed from here.
