The Olympic Stadium in Athens is a huge sports complex. It hosted the 28th Summer Olympic Games in Athens in 2004. On the eve of the game, the complex was completely reconstructed according to the project of the Spanish architect, who managed to build something light, airy and weightless from heavy metal structures. The most impressive was the Wall of Nations - a structure made of steel pipes that can change in waves, creating beautiful chiaroscuro on the main pedestrian path and the Square of Nations.→
