The Olympics give the host country a unique opportunity to show off not only their world-class athletes, but state-of-the-art facilities as well, which was exactly the purpose of the Dominque Perrault Olympic Tennis Centre in Madrid.
After three consecutive unsuccessful bids for the summer Games, losing out recently to London and Rio, this stunning stadium may not be shown off during the Olympics, but it will still be a spectacular experience for sporting event goers of today. Home to three tennis courts with three separate roofs of different shapes, the building has an unparalleled chameleon-esque character to it.
Since the roof of the centre has an impressive 27 different configurations, the building will never go out of style. If Madrid should ever succeed in securing a Games bid, the 'Magic Box' will certainly be an as buzzed-about monument as the 'Water Cube.'
