Museu de Portimão

Housed in a 19th-century fish cannery, the ultramodern, award-winning Museu de Portimão is the city's number-one draw. The museum focuses on three areas: archaeology, underwater finds and, the most fascinating, a re-creation of the fish cannery (mackerel and sardines). You can see former production lines, complete with sound effects – clanking and grinding and the like. An excellent video (in Portuguese) of the fishing industry reveals each step in the process, from netting the shoals to packaging.
