Dublin Castle is another top tourist attraction in Dublin, located just 15 minutes walk from Adelphi Guesthouse in Dublin City Centre. Dublin Castle is 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. 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.
The State Apartments, Undercroft, Chapel Royal, Craft Shop, Heritage Centre and Restaurant are open to visitors. (On occasions Dublin Castle can be closed at very short notice for Government business).
Guided tours take visitors through the grounds, sharing the history and ever-changing purpose of each building. Most notable is the story behind the Record Tower, the only remaining building from the original medieval structure that has miraculously survived centuries' worth of fires and warfare that ravaged the other buildings. Other noteworthy parts of Dublin Castle’s grounds include the State Apartments, Chester Beatty Library, and the Dubhlinn Gardens, which now grow over the spot where there was once a black pool, or "dubh linn", from which the city of Dublin gets its name.
