The modern Museu de Portimão, housed in a 19th-century fish cannery, is one excellent reason to visit Portimão. The museum focuses on three areas: archaeology, underwater finds, and, the most fascinating, a recreation 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.
