Dublin Castle

Dublin Castle has stood at the heart of the city for over 800 years and tells Ireland's history like almost nowhere else: from a Viking settlement, through centuries as the seat of English and then British rule, to today's role as a venue for state receptions and the inauguration of the President of Ireland. Centrally located on Dame Street, it's an easy addition to a walking tour of the old town.

Important: closed in 2026

Because of Ireland's EU Council presidency, Dublin Castle is serving as a conference venue throughout 2026 and is closed to the public. From 5 May 2026 the State Apartments close first, and from mid-June the entire site closes until 31 December 2026. Public tours are expected to resume from January 2027.

• If you're visiting Dublin in the second half of 2026, plan around this or pick an alternative.
• Check dublincastle.ie before you travel, as the dates can shift.
• Good substitutes nearby are Christ Church Cathedral or Trinity College with the Book of Kells.

History

The castle was built in the early 13th century on the remains of a Viking settlement and remained the seat of English, later British, administration in Ireland for centuries. Until 1922, the crown's viceroys governed from here. In 1907, Dublin Castle made criminal history when the Irish Crown Jewels vanished from a safe and have never been found.

Following Irish independence, the castle was formally handed over to the new government in 1922. Since then it has served as a stage for state receptions and the inauguration of Ireland's president. Its courtyards remain freely accessible and continue to form a political focal point of the Republic.

What to expect

The visit takes you through the lavish state rooms and beneath the castle into its medieval layers. Highlights include:

• State Apartments: the ceremonial rooms with chandeliers and paintings, including St Patrick's Hall, where presidential ceremonies still take place today.
• Chapel Royal: the neo-Gothic castle chapel from 1814, with fine stonework and ornate wood interiors, accessible only on the guided tour.
• Viking excavations: beneath the castle lie remains of the city wall and the earliest settlement, also part of the guided tour; access is via stairs only.
• Dubh Linn Garden: the garden behind the castle sits on the site of the old "black pool" that gave Dublin its name, and is free to enter.
• Chester Beatty: right next door, the Chester Beatty displays manuscripts and religious art spanning 4,500 years, with free admission.

Self-guided or guided

There are two separate tickets, and the difference is worth weighing up:

• The self-guided tour (€8 for adults) covers the State Apartments alone. You explore the rooms at your own pace, with a free official self-guiding app available to download.
• The guided tour (€12) is the only option that opens every part of the site, adding the Viking excavations and the Chapel Royal. It's a separate ticket category and isn't included in the self-guided price.

If you want the full picture of the castle, the guided tour is the better choice. If the grand state rooms are your main interest, the cheaper self-guided option is enough.

Visiting and practical tips

Dublin Castle is open year-round, daily, from 09:45 to 17:45, with last admission at 17:15; tours run from 10:00 to 16:30. There's no seasonal variation in hours. Allow around one to two hours for the interior. Mornings and late afternoons are quieter than around midday.

• Tickets: bookable online from 15 days ahead through the official portal; only a limited number of same-day tickets are available at the desk. No official skip-the-line option is advertised.
• Accessibility: the State Apartments and Chapel Royal are fully accessible, as are the Coach House Gallery and the Dubh Linn Garden. The Viking excavation is reachable only via stairs.
• Without a ticket: the courtyards and Dubh Linn Garden are free to enter, and the neighbouring Chester Beatty has no admission charge.

The castle is just a few minutes' walk from Temple Bar, Trinity College and Christ Church Cathedral, making it an easy fit for a city walking tour. For more historic buildings, see the overview of Castles and Ruins; if you're planning to visit several top attractions, the Dublin Pass may pay off.
