This beautiful mason building was a former power station now transformed into a cultural centre. The original machinery has been restored to show how it al works. Makes for great photography. The second part is a more science exhibition to educate in how electricity works. Good fun. Also for kids.
Small museum (no endless galleries), interesting, fun and free!

It was a bit awkward to get to on public transport, but would be easy if you have a car, as there's parking close by. The museum tells a very educational story of how it used to be the main electricity generating plant for the city. You really get a good feel for the scale of the machinery, and how it must have been to work in. There's plenty of hands-on; kids of all ages would have a great time here.

Now the Museum of Electricity, the building hosted Lisbon's first real electrical central and it still exhibits Portugal's first computers, built during the 1950s. The building itself is a wonderful architectural piece work of art, a bricked building of stature, and ocasionally there are temporary exhibitions which are also of interest.

Long time ago it used to be the electricity factory. Nowadays this beautiful building has some of the best art exhibitions, like world press photo. There's a bar with esplanade inside and the factory museum also deserves a visit.
