Londonderry is the second largest city in Northern Ireland and the fourth largest city on the island of Ireland. The old walled city lies on the west bank of the River Foyle. The city now covers both banks with the population of the city proper being 83,652. In the 2001 Census, the Derry Urban Area had a population of 90,736.
Derry is one of the oldest continuously inhabited places in Ireland. The earliest historical references date to the 6th century when St. Columba, or Colmcille, founded a monastery here. But there is evidence of habitation thousands of years before that time.
