Derry is the second-largest city in Northern Ireland and the fourth-largest city on the island of Ireland. The name Derry is an anglicisation of the Irish name Daire or Doiremeaning "oak grove". In 1613, the city was granted a Royal Charter by King James I and gained the "London" prefix to reflect the funding of its construction by the London guilds. While the city is more usually known colloquially as Derry, Londonderry is also commonly used and remains the legal name.
The old walled city lies on the west bank of the River Foyle, which is spanned by two road bridges and one footbridge. The city now covers both banks (Cityside on the west and Waterside on the east). The district administered by Derry City and Strabane District Council contains both Londonderry Port and City of Derry Airport.
