Before 1923 this place was a peripherical area and it was a Piazza delle Armi, where military exercices took place. Then the area was bought by the Ente Autonomo Fiera Internazionale di Milano and it became its headquarter until 2006.
In 2004 the fair district starts to move to the new venue in Rho-Pero and the urban area of 240.000 mq becomes the subject of an international tender won by CityLife with a urban regeneration project by Zaha Hadid, Daniel Libeskind and Arata Isozaki.
Around the heart of the project, Piazza Tre Torri with its business and shopping district, a public park of 173.00 mq it has been developed, designed by the Gustafson Porter studio, as winner of an international tender, the concept of the park is based on the representation of the landscape of the region (Lombardy) both concerning the morphology and the selection of the botanical species.
