The city is currently officially named Londonderry. However, many people today refer to the city by the name Derry. For some, this naming dispute is a contentious issue. Actually, the name Derry is primarily used by nationalists in Northern Ireland, with unionists preferring the city's official name, Londonderry. The most visible sign of this dispute to the visitor is in the road signage; those pointing to the town from the Republic refer to it as "Derry", whilst across the border it is written as "Londonderry". It is not uncommon to see vandalised road signs - the "London" part of the name spray painted over on "Londonderry" road signs by nationalists, or "London" added to "Derry" signs by unionists.
