Housed in a 1901 dockside warehouse with a striking glass and slate extension, this museum's 15 hands-on galleries explore Wales' commercial maritime history and the impact of industrialisation on its people, making much use of interactive computer screens and audiovisual presentations. The effect can be a bit overwhelming, but there's a lot of interesting stuff here, including displays on the Welsh music industry (artefacts include Bonnie Tyler's gold and Duffy's platinum discs) and a section on 'women's work'.
