What is the name of the secret Assassin training headquarters in Assassin's Creed II?

Villa Auditore is the secret Assassin training headquarters in Assassin's Creed II.

Villa Auditore is located in the Tuscan town of Monteriggioni and becomes Ezio Auditore's base after he leaves Florence. His uncle Mario reveals the family's connection to the Assassin Brotherhood and begins training Ezio there. The villa serves as a safe house, planning center, and place to improve equipment and abilities.

Players can restore the surrounding settlement by investing in buildings and services. Renovation produces income and gradually turns Monteriggioni into a more useful headquarters. The villa itself is also connected to the Auditore family's history and contains rooms, weapons, and records that reinforce the story's family theme.

Monteriggioni is the town, while Villa Auditore is the estate within it. These names are related but are not interchangeable. Villa Medici is a real Renaissance landmark in Florence, not Ezio's Assassin headquarters.
