The World Cup has come and gone, but the Olympics are just a year away, so Rio is still in rejuvenation mode: in 2015, visitors will be welcomed by an unusual new structure, a fish-shaped marvel alongside the water conjured by Santiago Calatrava. Museu do Amanhã (the Museum of Tomorrow) will examine science, humanity, and how our choices and actions are impacting our future. Expect interactive exhibits dedicated to population growth, climate change, and human behavior—and to leave with a newfound awareness of our planet and resources.
