Mirador Torre Glòries
While most of the 34 levels in the shiny, gherkin-shape tower that pierces Barcelona’s skyline are out of reach (the Jean Nouvel--designed building is now a business center), the exception is a 30th-floor observation deck. You’ll find the expected panoramic views—and they do delight, especially during the pink hues of dusk. What you won’t expect is a multiplatform, suspended art installation that you can scramble up to feel eerily airborne: nerves and agility, withstanding. Called Cloud Cities, it’s a truly unique experience, as is the basement exhibition of real-time big data on the city, from air quality to how many planes are overhead.
