In Assassin's Creed II, Ezio Auditore's family villa and headquarters are called Villa Auditore.
The villa stands in Monteriggioni, a fortified Tuscan settlement that becomes Ezio's base after the Auditore family is forced to leave Florence. Ezio's uncle Mario oversees the property and introduces him to the wider Assassin conflict. As the game progresses, players can renovate Monteriggioni and restore shops, landmarks, and other parts of the estate.
Villa Auditore is often associated with Monteriggioni because the settlement contains it, but the names are not interchangeable. Monteriggioni is the broader fortified town, while Villa Auditore is the Auditore family residence inside it. The location also serves as a narrative link between Ezio's personal revenge story and the expansion of the Italian Brotherhood.
