The Mutua Madrid Open is played in the Caja Mágica, or Magic Box, a stunning stadium with retractable roofs to make the most of the sun when it shines and provide shelter when the heavens open. The Madrid tournament’s centre court has capacity of 12,500. As well as the imposing Manolo Santana, the venue has two other courts with retractable roofs; the Arantxa Sánchez Vicario and Stadium 3.
This feature is unique to the Madrid tournament and the Australian Open, which also has the option of playing three simultaneous matches should the weather take a turn for the worse. The Arantxa Sánchez Vicario Stadium and Stadium 3 have respective capacities of 3,500 and 2,500.
