Museu Nacional da Imprensa

The National Press Museum is a bit out on a limb, just upriver of the Ponte do Freixo road bridge, but worth a detour for the comprehensiveness of its displays. They focus on printing and related processes, starting with a tribute to Porto’s own Rodrigo Álvares, who in 1497 printed Portugal's first two books. There is also a cartoon gallery; the museum runs an annual Cartoon Festival, with competitors from around the world taking part. You could walk down to the museum from Campanhã rail station, but it’s not a particularly pleasant stroll; better to catch the ZR minibus from the Ribeira district.
