Trinity College is probably the best spot to kick off your Dublin tour. It's at the heart of the capital, packed full of incredible history, and it's the oldest university in Ireland having been founded in 1592 by Queen Elizabeth I. Occupying an enviable 40-acre site, Trinity retains some of its ancient seclusion of cobbled squares, gardens, and parks and is famed throughout the world for its collection of great treasures. These include, on permanent exhibition, the 9th century illuminated manuscript, the Book of Kells, the Books of Durrow and Armagh, and an ancient Irish harp. The priceless artefacts are displayed in the Treasury and the awe-inspiring 18th-century Long Room, which houses more than 200,000 of Trinity's oldest books and hosts regular literary exhibitions.
