Founded in 1592, Trinity College is Ireland's premier university. The college is situated in the heart of Dublin, and is a really interting place to take a seat and do some pople watching. There are beautiful buildings and a well kept green along with a 30m high Campanile. The main attraction of Trinity College is the Book of Kells, which is housed in the library, and can only be visited if you pay for a guided tour of the college. The Book of Kells is an illuminated manuscript which dates back to around AD 800, making it one of the oldest books in the world!
