Dublin Castle
Worth a stop, mostly for the medieval undercroft and the Chester Beatty next door, but only when the castle is open: the State Apartments and tours closed on 5 May 2026 and the full campus from mid-June, all through the end of December for the EU Presidency. The State Apartments are handsome but not unmissable if you have palace fatigue. Take the guided tour rather than self-guided so you actually get the undercroft, but first check the site is open at all before you plan around it.
This is not a fairytale castle, it is a working government complex with 800 years of layered history under one site: grand state rooms, a medieval undercroft, and a free, excellent museum on the grounds. The guided tour is the way to get the most out of it, since it opens up the undercroft and the chapel that self-guided tickets sometimes don't. Big catch for 2026: the State Apartments and guided tours closed on 5 May, and the entire campus, including the Chester Beatty next door, is shut to visitors from mid-June through the end of December for the EU Presidency, with tours due back in January 2027. Plan around that.
Worth it for
- History buffs who want the medieval undercroft and city wall
- Anyone who can catch the Chester Beatty while it is open
- Visitors who like a central, low-effort stop between bigger sights
You can skip if
- You have seen plenty of grand European state rooms already
- You only wanted a dramatic medieval fortress, since this is mostly Georgian
Our pick for Dublin Castle
This guided tour covers Dublin Castle alongside the Book of Kells at Trinity College, and its review record is deep enough to give you real confidence in what you are booking. A guide walks you through the castle's layered history, from the Norman foundations to the State Apartments, which makes the site legible in a way that wandering the courtyard alone does not. Pairing it with the Book of Kells in one morning is what most visitors end up doing anyway, and having a guide for both means you leave knowing what you actually saw.
If our pick doesn't fit
Gets you into the castle and Book of Kells before the crowds, though it has a much smaller track record than the standard tour.
Extends the same pairing of Dublin Castle and Book of Kells to include Christ Church Cathedral, at a slightly lower price.

Which ticket should you buy?
What it is
Dublin Castle was the seat of British rule in Ireland for centuries, handed over to the new Irish state in 1922. Today it hosts state events and presidential inaugurations, so parts can close at short notice. The look is mostly Georgian rather than medieval, because the original castle largely burned and was rebuilt, but the bones of the old fortress are still down there.
The visit splits into a few pieces: the State Apartments (formal reception rooms), the medieval undercroft (excavated remains of the original Viking-era and medieval defenses), the Chapel Royal, and the separate Chester Beatty museum on the grounds.
What to see
The State Apartments are the showpiece: chandeliered drawing rooms, the throne room, and St Patrick's Hall with its painted ceiling. They are genuinely grand, though if you have done a lot of European palaces they may feel familiar. The undercroft is the more interesting part for history people, where you stand among the foundations of the old castle, including a stretch of the original city wall and moat.
The Chester Beatty, on the castle grounds, is the sleeper hit and normally free. It holds an extraordinary collection of manuscripts, sacred texts, and art from across Asia, the Middle East, and Europe, and it has won awards as one of Europe's best museums. Note the 2026 closure, though, from mid-June to the end of the year.
Visiting and tickets
Outside the 2026 EU Presidency closure, you can do a guided tour (about 60 to 75 minutes, and the only way to reliably see the undercroft and chapel) or a cheaper self-guided ticket for the State Apartments. The courtyards and grounds are free to walk through. Tickets can be booked online a couple of weeks ahead and the guided tours have limited capacity, but note the State Apartments and tours closed on 5 May 2026 and the full campus from mid-June, all through the end of December, so check it is open before you count on it.
Because the castle is a live state venue, rooms occasionally close for official events. If a specific space matters to you, check the day before. Budget around an hour to 90 minutes for the castle, plus extra if the Chester Beatty is open during your visit.
Dublin Castle: FAQs
The guided tour (about 60 to 75 minutes) covers the State Apartments plus the medieval undercroft and the Chapel Royal. The self-guided ticket is cheaper but usually limited to the State Apartments and chapel, without the undercroft.
Not for much of it. The Chester Beatty is closed to the public from mid-June to the end of December 2026 for the EU Presidency. Outside that window it is free and does not require booking.
Yes. The courtyards and grounds are open to the public at no charge. Only the State Apartments, undercroft, and chapel tours are ticketed.
Yes. The castle still hosts state events and inaugurations, so individual rooms or the whole apartments can close at short notice. Check ahead if a specific space matters to you.
About an hour to 90 minutes for the castle. Add more time if the Chester Beatty is open during your trip, since it can easily fill an hour on its own.
It is on Dame Street in the city center, a short walk from Temple Bar and Trinity College. The nearest Luas stops are a few minutes away on foot, and most central walking routes pass close by.
The courtyards are free and pleasant for a short wander, so if you only want the setting you can skip the ticket. Paying gets you the State Apartments, with rooms like St Patrick's Hall and the Portrait Gallery, and the guided tour adds the medieval Undercroft and the Gothic Chapel Royal that you cannot see otherwise. Note that the State Apartments and full campus close for Ireland's EU Council Presidency across much of 2026, so check availability before counting on an interior visit.
The courtyards are an outdoor public space and are usually walkable into the evening, when the buildings are softly lit and quieter for photos. The tours and the State Apartments run in daytime hours only, so there is no standard nighttime interior visit apart from occasional special events such as Culture Night. During the 2026 EU Presidency closure the campus itself may be off limits, so check the day you plan to go.
The open courtyards and the Dubhlinn Gardens behind the castle give younger children room to move for free, which suits a short stop. The paid State Apartments are a calm, formal walk through grand rooms and tend to work better for older children who are into history than for restless toddlers. Keep it brief and pair it with somewhere more active nearby if the group has little ones.
