Londonderry Port (Port Code:GBLDY) now operating as 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. 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.
The Port today is principally an import facility although a number of products are also exported. The relocation to Lisahally therefore, has been particularly important for bulk commodities that can now be sourced directly from deep-sea destinations and has enabled Port users to realise economies of scale and to source markets from further-a-field. Londonderry Port handles a wide range of liquid bulk and dry bulk trades, but does not at present handle unit load trades. The port throughput figure in 1999 was 1,216,277 tonnes having grown from some 760,000 tonnes over 12 years.
