1. City of Arts and Sciences (CAC)
What is it? Valencia-native Santiago Calatrava designed this blazing white complex for the arts and sciences, an artful arrangement of giant sculptural shapes that house, among other attractions, an aquarium that looks like a wave, an opera house in the form of a ship, and a giant eye-cum-planetarium.
Why go? Go to watch the beluga whales wheel around the giant aquarium, have fun at the interactive science museum, or simply admire the daring contemporary architecture of what Spaniards voted one of the ‘12 Treasures of Spain’.
