Dublin, capital of the Republic of Ireland, is on Ireland’s east coast at the mouth of the River Liffey. Its historic buildings include Dublin Castle, dating to the 13th century, and imposing St Patrick’s Cathedral, founded in 1191. City parks include landscaped St Stephen’s Green and huge Phoenix Park, containing Dublin Zoo. The National Museum of Ireland explores Irish heritage and culture.
The Republic of Ireland occupies most of the island of Ireland, off the coast of England and Wales. Its capital, Dublin, is the birthplace of writers like Oscar Wilde, and home of Guinness beer. The 9th-century Book of Kells and other illustrated manuscripts are on show in Dublin’s Trinity College Library. Dubbed the "Emerald Isle” for its lush landscape, the country is dotted with castles like medieval Cahir Castle.
