The Prada Foundation in Milan has been promoting contemporary art in all its forms for twenty years. The Foundation is located in an industrial archeology complex that relates to the city. The venue was designed by the OMA architecture studio, led by Rem Koolhaas. The Foundation is divided into three buildings: the Podium, the Cinema and the Tower. The Tower, in particular, marks the completion of the Milan office. The permanent collection includes works from the 20th and 21st centuries by some of the most important international artists, such as: Jeff Koons, Walter De Maria, Pino Pascali, Damien Hirst and Carsten Höller. The Prada Foundation hosts several temporary artistic and cinematographic events, as well as temporary exhibitions with international artists.
