Derry, officially Londonderry, 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 Doire meaning "oak grove". In 1613, the city was granted a Royal Charter by King James I and the "London" prefix was added, changing the name of the city to Londonderry. While the city is more usually known 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, along with Inishowen.
