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 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.
