See the Book of Kells, a 9th centuty manuscript that is famous for its pictures.. ah, it's of the Gospels. Anywho, it's really tiny, but the illustrations (that you can see anyway) are wonderful. You can find it in the Old Library of Trinity College (part of the University of Dublin). It's open 7 days a week.
Fondest memory: While walking in a park, my father saw someone he knew from work, halfway across the globe! Talk about coincidence! :)
Have a walk around Trinity College, and feel the antiquity of it's old buildings. The 'Book of Kells' is kept there in the Library.
Fondest memory: Just being there, the river,the wonderful lilting accent of the Irish, and of course, my first Guiness in an Irish Pub, always tastes the best.
