Northern Ireland and the Republic of Ireland have different currencies.
In the Republic of Ireland the currency used is the Euro and in Northern Ireland the currency used is the Pound Sterling.
The Republic of Ireland lies in the north Atlantic Ocean and is separated from Britain by the Irish Sea to the east. The northeastern part (Northern Ireland) is part of the United Kingdom. The country has a central plain surrounded by a rim of hills and mountains offering some of the most varied and unspoilt scenery in Europe. Quiet sandy beaches, semi-tropical bays warmed by the Gulf Stream, and rugged cliffs make up the 5600km or 3500 miles of coastline.
The main river in Ireland is the River Shannon, 386 km (240 mi), the longest river in either Ireland or Great Britain, which separates the boggy midlands of Ireland from the West of Ireland. The river develops into three lakes along its course, Lough Allen, Lough Ree, and Lough Derg. Of these, Lough Derg is the largest.
