The Long Room in Trinity College is the source of heaps of wanderlust.


Well, it could be down to it’s uncanny resemblance to the library in the Harry Potter series.

Or maybe it’s the sheer number of beautiful old books that line its walls.

All I’ll say before we dive into the guide is that it’s well worth visiting.

Some quick facts about the Long Room

  • It was built between 1712 and 1732
  • The room stretches for an impressive 65 metres
  • It’s packed with 200,000 of the library’s oldest books.

A visit to the Long Room in Trinity College is hands-down one of the best things to do in Dublin.

The main chamber of the library is known as the Long Room.

This room stretches for an impressive 65 metres and is packed with 200,000 of the librarys oldest books.


I’ll just let that sink in for a sec.

About the Long Room

The Long Room was built between 1712 and 1732.

At the time, the ceiling was flat, and bookshelves could only be found on the lower level.

By the 1850s, the shelves were rammed with books.

So, in 1860, the roof of the library was raised to facilitate the construction of the barrel-vaulted ceiling and upper gallery bookcases that you can see in the photo above.

Busts and Books

A collection of marble busts began in 1743 when 14 busts were commissioned from Peter Scheemakers, a renowned Flemish sculptor.

The busts depict many of the great philosophers and writers of the western world along with a number of men that were connected with the college.

Some of the other treasures that you can check out are:

  • One of the few remaining copies of the 1916 Proclamation of the Irish Republic
  • A harp that’s the oldest of its kind in Ireland (thought to date back to the 15th century)

This was one of the first articles ever published on this website.

Since then (and thanks to the page ranking in Google for ‘Trinity College Library Harry Potter’) I’ve been getting email after email from people asking whether or not the movie was shot here.

Although I wish there was a Trinity College Harry Potter link, there isn’t.

The Long Room just resembles the library used in the filming of the Harry Potter movies.
