CosmoCaixa Museum of Science

This guide to CosmoCaixa Museum of Science in Barcelona starts with the building's earlier life: a brick asylum that sheltered the city's blind residents for seventy years, until it closed in 1979. It traces how architects Esteve and Robert Terradas turned that legacy into an underground science museum, carving new galleries beneath the square without disturbing the original facade. Along the way it visits a flooded recreation of the Amazon rainforest and a wall of rock slices drawn from around the world.
