Torre de Comunicacions de Montjuïc

Rising from the Olympic Ring, Calatrava's tower carried the television signal for the 1992 Games and was conceived as both functional infrastructure and public sculpture, its tilted, bone-like white form doubling as a sundial that casts a shadow across the plaza below at certain times of day. It's not open to visitors inside, so the appeal is purely architectural, best appreciated by walking around its base or viewing it from a distance against the sky. Reviewers describe the surrounding area as calm and open, a contrast to more crowded parts of Montjuïc, though some note the walk from the castle can involve a few unplanned detours. A quick, free stop that pairs naturally with the rest of the Olympic Ring.
