The Trinity College is an university, rich of history and you can visit all of it! Here you can find the Book of Kells, a 9th century manuscript that documents the four Gospels of the life of Jesus Christ. The Book of Kells is Ireland’s greatest cultural treasure and the world’s most famous medieval manuscript. That’s a must-see on the itinerary of all visitors to Dublin! A little curiosity: Harry Potter was recorded in the college’s library!
