Magic Box of Madrid

The Caja Mágica has been presented as the most modern tennis facility in the world. The venue has annually hosted the Mutua Madrid Open since 2009. Made entirely of steel, wood and glass, the sports complex was designed by French architect Dominique Perrault. The name Madrid Caja Mágica is associated with the envelope of the sports halls, to which it gives a dynamic and changing appearance.
Conceived on a 16.5-hectare surface area on former derelict land located between the freeway and the railway wastelands, the Olympic Tennis Center with a surface area of 100,000m2 is composed of 3 indoor and outdoor tennis courts for 20.000 spectators (12,000, 5,000 and 3,000 respectively), 16 outdoor tennis courts, five indoor courts for 350 spectators each, six training courts, an indoor swimming pool, as well as the headquarters of the Madrid Tennis Federation, a tennis school, a tennis club, a press center, reserved spaces and restaurants.

The three tennis courts adapt to the different uses of the sports complex.
