Trinity & Castle in Dublin — FAQ

What is the Book of Kells?
The Book of Kells is a stunning 9th-century illuminated manuscript of the Gospels, displayed at Trinity College alongside the magnificent Long Room library — one of Dublin’s must-sees.
Should I book Book of Kells tickets in advance?
Yes — the Book of Kells and Long Room use timed entry that sells out, so booking ahead is recommended, especially in peak season.
What is there to see at Dublin Castle?
Dublin Castle’s highlights are the State Apartments, the medieval undercroft and the Chapel Royal, telling 800 years of Irish history at the heart of the capital.
