Ireland is an island nation on the westernmost edge of Europe. It is the continent's second largest island (after Great Britain). The Republic of Ireland occupies 80 percent of this landmass, while a large chunk of land in the north is part of the United Kingdom.
Ireland is known for its wide expanses of lush, green fields. In fact, its nickname is the Emerald Isle. But there are also large areas of rugged, rocky landscape. About 15,000 years ago, Ireland was completely covered by thick glaciers. The movement of these giant sheets of ice stripped the soil, leaving huge tracts of flat, limestone pavement.
Ireland’s capital is Dublin, a populous and affluent city whose metropolitan area is home to more than one-fourth of the country’s total population. The city’s old dockside neighbourhoods have given way to new residential and commercial development. Cork, Ireland’s second largest city, is a handsome cathedral city and port in the southwest. Other principal centres include Waterford, Wexford, and Drogheda on the east coast, Sligo in the northwest, and Limerick and Galway in the west.
