What is the name of the Assassin's Creed II town that becomes Ezio's home base?

Monteriggioni is the town that becomes Ezio's home base in Assassin's Creed II.

Ezio reaches the Tuscan hill town after leaving Florence with his uncle Mario Auditore. Mario serves as the town's lord and reveals the Auditore family's connection to the Assassin tradition. Ezio later helps restore Monteriggioni and uses the Villa Auditore as a headquarters.

The villa provides access to upgrades, shops, training, and income generated by improving the settlement. Monteriggioni therefore functions as more than a historical location: it is the game's central management hub and a place connected to Ezio's family history.

Players sometimes confuse Monteriggioni with Masyaf, the fortress associated with Altaïr in the first game. Monteriggioni is in Tuscany and belongs to Ezio's Renaissance story, whereas Masyaf is a Syrian mountain settlement linked to the earlier Assassin Mentor Al Mualim.
