What's that, you say? You've checked out of your hotel but your bus doesn't leave for a few hours? Well my friend, you're in luck, the Galway Museum is a great spot to fill those last few "what'll I do?" moments before you head out of town.
It has three floors of exhibits, mostly about, surprise, the History of Gallway. But it makes the subject really come to life and covers the medieval commercial and modern military role the city has played over the centuries.
You can learn everything you ever wanted to know about designs for hide-covered boats (every little seaside town has a distinct style, really!), and as of this writing they give an ultra-modern nod to urban art in their graffitti exhibition. Including a place to do your own (at least, that's what the little sign seemed to be implying, and there were no cameras...)
Bottom Line: I would definitely add this to my "Free Stuff to do in Dublin" list except, well, it's in Galway..
