Museu do Amanhã, or Museum of Tomorrow, is a science museum on the Rio de Janeiro waterfront at Praça Mauá, dedicated to exploring humanity’s future through the lens of sustainability, technology, and the natural world. Designed by Spanish architect Santiago Calatrava, its striking, wing-like structure extends out over the water and has become a landmark of the revitalized Porto Maravilha harbor district.
Inside, interactive exhibits examine themes such as climate change, biodiversity, and how human choices today shape possible futures, using large-scale multimedia installations rather than traditional static displays. The museum is open Tuesday through Sunday from 10 AM to 6 PM, and admission is free every Tuesday, with a ticketed entry fee on other days; discounted tickets are available for students, young people, and Rio residents.
Most visitors spend 2 to 3 hours moving through the museum’s main exhibition halls, making it a comfortable half-day stop when paired with a walk along the nearby waterfront.
