The Milan North Park business centre is in a modern glass-fronted 12-storey building, one of four towers that form part of an imposing business district surrounded by parks and gardens, north of the city. Milan is expanding its traditional fashion, automotive, textile and financial industries into new technologies, food production, logistics and other sectors. There are five 'incubator clusters' focusing on ICT, energy, fashion, biotechnology and life sciences and nutrition, to provide comprehensive support networks for new enterprises. This is linked to Milan's research institutes and fast developing CityLife trade fair district, with its massive convention centre. The Milan North Park business centre is within easy reach of motorways surrounding the city and Malpensa International Airport, redeveloped in 1998 to become Italy's second most important passenger airport.
