1 Best Sight in Piedmont and Valle d'Aosta, Italy

The richly decorated House of the Green Count, in the oldest part of Rivoli, attests to the wealth and importance of its onetime owner, Amedeo VI of Savoy (1334–83). Legend has it that the count attended tournaments dressed all in green, hence the name. Inside, a small gallery occasionally hosts temporary exhibitions, which may increase the entrance fee.
