If you're wondering how to get your young kids interested in art and science, this unusual museum – actually two museums in one – is an excellent place to start. Housed in an old penitentiary built in 1909, it's part children’s museum and part art gallery. Small kids will love the hands-on exhibits related to science, geography and natural history, while grown-ups will enjoy the unusual juxtaposition of contemporary art in abandoned prison cells.
