Turin's former Fiat factory, one of Italy's most praised examples of early-20th-century industrial architecture, is 5km south of the city centre. It was redesigned by architect Renzo Piano in the 1980s to house an exhibition centre, a university campus and hotels. While still starkly beautiful, the shopping mall that occupies much of its accessible space is less than inspiring.
Lingotto is on the M1 metro line and easily accessible from the city centre.
