Housed in a 1901 dockside warehouse with a striking glass and slate extension, this museum's hands-on galleries explore Wales' commercial maritime history and the impacts of industrialisation on its people, using interactive computer screens and audiovisual presentations. There's some fascinating stuff here. A highlight is the Penydarren Steam Locomotive, Richard Trevithick's steam machine that in 1804 chugged from Penydaren to the Merthyr-Cardiff Canal on the world's first railway journey.
Displays on the Welsh music industry (artifacts include Bonnie Tyler's gold and Duffy's platinum discs) also catch the eye.
