The Centro Direzionale di Milano is a business district (quartiere) in Milan, Italy, part of the Zone 9 administrative division. It is located north-west of the city centre, between the major railway stations of Milano Centrale and Milano Porta Garibaldi. The district developed in the second half of the 20th century; its realization was planned by the city administration to relieve congestion in the city centre by moving business and tertiary activities in the new area. Coherently with this plan, the district is mainly occupied by modern office buildings, including several of Milan's skyscrapers.
