The Meeting Centre of Milan MiCo is situated inside the existing Pavilion 6 of Fiera Milano City. With 18,000 seats subdivided into 70 modular rooms, an auditorium of 1,500 seats and a plenary chamber of 5,000 seats, it is the biggest convention centre in Europe. For the redefinition of the internal spaces, on the basis of its adjustment to the convention activities, the following criteria have been taken into consideration: to obtain a continuity with the convention centre of Pavilion 17; to maintain the building blocks of the existing, realizing the transformations of the internal sections through light and modular structures, respond to the present functional exigencies of the convention and exhibition activities.
