The Long Room at Trinity College is one of the most beautiful libraries in the world.
It holds more than 200,000 antiquarian books, including the Book of Kells — a 9th-century illuminated manuscript containing the texts of the four Gospels, created by Irish monks. It’s considered one of the most beautiful manuscripts in the world, with extraordinary calligraphy, ornament and detail.
Bram Stoker and Oscar Wilde both studied here, back before they were famous.
Right now the place is closed to visitors — restoration work is under way to strengthen the building and protect the book collection. It’s due to reopen in 2028–2030.
