Because of its location, the Monash Centre does not have on-campus parking. However there is parking nearby.
Enter the city walls at Via Frascati and continue straight until Piazza dell'Imperatore where there are a few pay car parks. There are larger pay car parks in Piazza Mercatale and in Via Arcivescovo Antonio Martini.
The Monash Centre and main car parks are marked on the Prato city map (pdf, 1 page, 372kb). For instructions on getting to Prato, see the conference's travel advice.
