Derry or Londonderry (Irish: Doire or Doire Cholm Chille, meaning Oak wood of Colm Cille), often called the Maiden City, is a city in Northern Ireland. The old walled city of Londonderry lies on the west bank of the River Foyle, and the present city now covers both banks (Cityside to the west and Waterside to the east) and is connected by two bridges. The district extends to rural areas to the southeast of the city. The population of the city proper was 83,652 in the 2001 Census. The Derry Urban Area (including Culmore, New Buildings and Strathfoyle) had a population of 90,663, and is the second-largest city in Northern Ireland , the fourth on the island of Ireland. It is one of the only places in Europe not to have its defensive walls breached (though the original fortified gates have been replaced). Derry is very near the border with County Donegal in the Republic of Ireland and also serves the west of County Londonderry. The district is run by Derry City Council and has an airport, City of Derry Airport, and a seaport, Londonderry Port.
