Derry or Londonderry (Irish: Doire or Doire Cholmchille, meaning "Oak wood of Columba") often called the Maiden City, (a reference to its walls remaining unbreached during the Siege of Derry in 1689) is a city in Northern Ireland.
The old walled city of Londonderry lies on the west bank of the River Foyle, with the location of old Derry on the east bank; the present city now covers both banks (Cityside to the west and Waterside to the east) and the river is spanned by two bridges.
