Dublin Castle

A Castle That Shaped a Nation

Dublin Castle was first established in the early 13th century on the orders of King John of England. It stood on the site of a Viking settlement and served as a fortress, a treasury, a court, and the seat of British administration in Ireland for over 700 years.

Though only one of its original medieval towers remains—the Record Tower—what you see today is a striking mix of architectural styles. From Georgian opulence to medieval stonework, the castle reflects the layers of history that have shaped Ireland.

Power, Politics, and Ceremony

For centuries, Dublin Castle was the centre of British rule in Ireland. Here, viceroys governed in splendor, grand banquets were held, and decisions that impacted the entire country were made behind heavy wooden doors. When Ireland gained independence in the 20th century, the castle’s role changed dramatically—it’s now a site of state functions, including presidential inaugurations and official ceremonies.

You’ll walk through rooms that have hosted foreign dignitaries and heads of state, but also once echoed with whispers of rebellion and resistance. The State Apartments, with their glittering chandeliers and lavish décor, are a particular highlight.

Things to See and Do

Start with a guided tour—it’s the best way to appreciate the hidden stories behind the grand façades. Highlights include the State Apartments, the Gothic Chapel Royal with its intricate plasterwork, and the medieval undercroft, where you can see remains of Viking and Norman defences.

The Dubhlinn Gardens behind the castle offer a peaceful escape, and the name “Dubhlinn” is where the city of Dublin gets its name—from the ancient “black pool” that once sat on this site.

You might also catch an exhibition or event, as the castle regularly hosts art shows and cultural festivals throughout the year.

Practical Tips

Dublin Castle is open year-round and easy to access on foot from anywhere in the city centre. Tours run frequently and are well worth joining. Tickets can be booked online or purchased on-site.
