The historical Perugia company offers as a prize six coffers filled with chocolate, to be opened by six lucky keys. Only one of the coffers will be placed in the city’s historical centre, while the other five will be held in the Casa del Cioccolato Perugina at the San Sisto plant. To open them, visitors will have to be lucky enough to find the right keys, although non-winners too will console themselves with the Corso Vannucci made entirely of chocolate from the keyhole and, most importantly, will get the chance to participate in the numerous initiatives planned at the Casa del Cioccolato Perugina, where the established Scuola del Cioccolato Perugina (Perugia school of chocolate) and the Museo Storico (historical museum) of the company, that last year celebrated its 100th anniversary, are hosted.
