The piazza in Sant'Eufemia a Maiella, located deep within Italy's central Majella National Park, will be covered with a 650-sq-m (7,000-sq-ft) board as part of the event later this month, the local Il Centro website reports . It's billed as the biggest game of Risk in the world by the event's organisers . Artist Liberio Furlini spent 15 days painting the huge political map of the world used in the game. Super-sized playing pieces designed to fit with the gigantic board will be used by those taking part.
