Milan-based architecture firm Onsitestudio have designed a new training campus for Italian Serie A soccer club U.S. Sassuolo Calcio. Located in the town of Sassuolo, in the Emilia-Romagna region, and inaugurated in 2019, it is a functional-modernist yet highly atmospheric structure that provides the professionals of U.S. Sassuolo Calcio with state-of-the-art training facilities and offices. As part of a pioneering social engagement of the club, its playing fields and other amenities are also available to local amateur teams and for recreational sports. This book features the Mapei Football centre through newly taken colour and black-and-white photographs by Stefano Graziani and Filippo Romano, as well as floorplans, sections, and construction detail drawings. Complementary essays are contributed by Onsitestudio's founding partners Giancarlo Floridi and Angelo Lunati, British historian and football expert John Foot; and Italian architect and intellectual Pier Paolo Tamburelli.
