The sole college of the University of Dublin, Trinity was founded by Queen Elizabeth I in 1592.
The reason most visitors venture to Trinity is to take a look at the Book of Kells, the renowned "illuminated" manuscript created by monks around AD 800. It's one of the oldest books in the world and one of the most exquisite.
The Book of Kells is on display at the Old Library, and the ticket price includes admission to the Long Room, a striking space that contains 200,000 of the college's oldest books.
Open Monday to Saturday 9.30am-5pm, Sunday noon-4.30 pm (from 9.30am June to September). College Green (2). Phone 608 1177.
