The Alamillo Bridge in Seville, created in 1992 by world-famous architect Santiago Calatrava, is a sculpture as much as a way to cross the street. With its unique asymmetric pylon, this cable-stayed bridge acts as a gateway to the city and is an example of creative architecture that successfully combines practicality and visual appeal.
