The Portello project started in 2000 and occupies an area of 240,000 sqm.
The area once housed the Alfa Romeo and Lancia factories. This site represents the new north gate of the city, which leads to the motorway system, and dialogues with the great diagonal in Gino Valle general intervention plan, that will be the new threshold and connection between the Trade Fair and the new “Piazza Mercato” (market square).
The park under construction is about 70,000 sqm and can be considered a landmark that indicates the access to the city.
The designer Charles Jencks outlined the morphological modeling of the hill, which creates a system of diagonal continuity with Monte Stella, the historically famous artificial hill created by Piero Bottoni after World War II.
