Dublin Castle is in the heart of historic Dublin. In fact the city gets its name from the Black Pool - 'Dubh Linn' which was on the site of the present Castle garden.
The Castle stands on the ridge on a strategic site at the junction of the River Liffey and its tributary the Poddle, where the original fortification may have been an early Gaelic Ring Fort.
Dublin Castle: Originally built in the 13th century on a site previously settled by the Vikings it functioned as a military fortress, a prison, treasury, courts of law and the seat of English Administration in Ireland for 700 years. Rebuilt in the 17th, 18th, 19th and 20th centuries, Dublin Castle is now used for important State receptions and Presidential Inaugurations.
