This business park comprises four skyscrapers built on the former site of Real Madrid Sports City, the team’s previous training complex. The towers include Torre Foster, Torre PwC (formerly Torre Sacyr Vallehermoso), Torre de Cristal and Torre Emperador Castellana (previously Torre Espacio). In 2021, they were joined by a fifth building, Caleido, which mainly houses offices but also amenities such as a hotel and garden. Each skyscraper features multiple levels of underground parking. The construction of the first four buildings began in 2004 and was completed in 2008.
