Dublin Castle is a major Irish governmental complex, formerly the fortified seat of British rule in Ireland until 1922. The castle is one of the oldest buildings in Ireland and fulfilled many roles throughout its history.
It has served as a royal residence, a military base, and the seat of English Administration in Ireland up until the free state of Ireland was formed. Dublin Castle also played a significant role in the Easter Rising.
Today, Dublin Castle is used for a wide variety of government functions and ceremonies. The grounds also hold two museums, gardens, state apartments and are home to a world-class collection of Chester Beatty Library. The grounds of the site are free to explore, however if you wish to take a tour of the State Apartments you must purchase a ticket.
