What is the name of the Assassin Brotherhood's hideout in Assassin's Creed II?

Villa Auditore is the Assassin Brotherhood's main hideout in Assassin's Creed II.

The villa is located in Monteriggioni, Tuscany, and belongs to Ezio Auditore's family. After Ezio leaves Florence, his uncle Mario brings him to the estate and reveals the family's connection to the Assassins. The property becomes a safe base for equipment upgrades, training, and story planning.

Players can renovate Monteriggioni by investing in shops and buildings around the villa. Those improvements generate income and make the settlement more valuable as the game progresses. The location therefore functions as both a narrative home and a gameplay management system.

Monteriggioni Castle is the fortified town containing the estate, so it is a plausible but less specific description. Masyaf is associated with Altaïr, while the Davenport Homestead belongs to Connor's story in Assassin's Creed III.
