Dublin Castle, Medieval castle in central Dublin, Ireland
Dublin Castle is a fortified complex in central Dublin that combines medieval towers, Georgian state apartments, and modern administrative buildings around two main courtyards. The site spans several levels and connects architectural styles from different eras.
The fortification was established from 1204 as the seat of English administration and remained a center of British rule for over seven centuries. After Irish independence in 1922, the complex passed into the hands of the new state.
The castle stands beside the dark pool, Dubh Linn, on the River Poddle that gave Dublin its name; the Poddle now runs beneath the complex. Since 1938 each President of Ireland is inaugurated here, and the State Apartments hold an accredited museum collection.
Guided tours run for about an hour, while the courtyards and outer areas remain accessible without booking. A visit works best on weekdays, when fewer people are around.
Below the courtyards lies a medieval undercroft holding remains of Viking and Norman structures from the 13th century. These underground rooms show parts of the original walls and earlier foundations.
