Dublin, Ireland

Dublin wears its maritime history close to the surface. East Wall and Ringsend have old shipyards and workshops mixed with new industry. Poolbeg Lighthouse at the harbour mouth is a good spot for watching ships enter on the tide. If you can take the time and want something cultural, rather than the usual Guinness-and-pubs routine (although there is NOTHING wrong with that!), take a look at the Jeanie Johnston replica ship and museum.
