When I visited Dublin last year, we stopped at Trinity College to see The Book of Kells. I hadn't heard of it prior to our visit, but they were pretty amazing to see. But my favorite part was going through the college's library. It was like my childhood fantasy come true. (My childhood fantasy was to have the library from Disney's Beauty and the Beast. Actually, I still want it.) This library had two stories with a curving staircase to reach the books on the top shelves. It's still one of my favorite parts of Dublin.
