Let's make this birthday one to remember.

73 years old (Born on July 28, 1951)

Happy Birthday, Santiago Calatrava! Your genius has given us architectural wonders so breathtaking they deserve their own postal codes. From bridges that elegantly connect two shores to train stations impressive enough for people to miss trains intentionally—your masterpieces turn mundane commutes into art gallery tours!

Let's raise a toast beneath the soaring arches of Toronto's Allen Lambert Galleria and signal our best wishes from Barcelona’s unforgettable Montjuic Communications Tower—a structure clearly inspired by alien-friendly antennas or perhaps futuristic ice cream cones. Here's hoping this birthday tops your tallest designs—and unlike some modern constructions, doesn't go wildly over budget!
