On a whim, my wife, 3 kids, and myself stopped in at this museum. We all consider it to be the most bizarre and best thing we saw on our whole trip around Ireland! This place has everything: the largest wooly mammoth skull and tusks in the world, a large and beautiful ancient Celtic jewelry collection, stone age, bronze age, fossils, etc.. The gift shop also sells fossils, antiques and weird/cool stuff that we didn't see anywhere else. The guy who runs the place is also a real character. Ask to see his goat Sally.
