This innovative design was the winner of an architectural competition organised by the city of Barcelona to create a monumental technological element that would operate during the 1992 Olympic Games.

The aim was to create a complex which would form part of Spain's global communications infrastructure, and has managed to become a symbol of the city as it entered the 21st century.
