Museum of Tomorrow is a museum built in the municipality of Rio de Janeiro, Brazil. The building, project of the Spanish architect Santiago Calatrava, was erected next to Plaza Mauá, in the port area (more precisely in Píer Mauá).
The institution's proposal is to be a museum of arts and sciences, as well as exhibits that warn of the dangers of climate change, environmental degradation and social collapse. The building has solar pimples that move along the skylight, designed to adapt to changing environmental conditions. The main exhibition is mostly digital and focuses on ideas rather than objects.
