In Assassin's Creed II, which Renaissance city contains the Auditore family villa?

In Assassin's Creed II, the Renaissance city containing the Auditore family villa is Monteriggioni.

Monteriggioni is a fortified hill town in Tuscany that serves as Ezio Auditore's family stronghold. Ezio's uncle, Mario Auditore, controls the settlement and welcomes Ezio after the tragedy that destroys much of the Auditore household. The villa becomes a recurring base for missions, upgrades, and story conversations.

The game separates Monteriggioni into a town and the Villa Auditore estate. Players can invest money in the settlement, repair buildings, and improve shops, which gradually increases the income collected from the town. This makes the location both a narrative refuge and a management system.

The real Monteriggioni is a medieval walled town near Siena, Italy. Assassin's Creed II also visits Florence, San Gimignano, Forlì, and Venice, so players sometimes confuse the villa's location with the game's larger Italian settings. Monteriggioni, however, is the Auditore base rather than Ezio's birthplace.
