In Assassin's Creed Brotherhood, what is the name of Ezio Auditore's headquarters in Rome?

Ezio Auditore's headquarters in Rome is the Tiber Island hideout in Assassin's Creed Brotherhood.

The hideout is located on Tiber Island, a small island in the Tiber River near the center of Rome. Ezio uses it as a base while rebuilding the Assassin Brotherhood and opposing the Borgia family. The location serves as a meeting place, planning center, and access point for several activities.

Brotherhood, released in 2010, continues Ezio's story after Assassin's Creed II. Rather than moving to a collection of major cities, it focuses heavily on Rome, where the player liberates districts, recruits new Assassins, and sends them on missions across Europe.

The hideout should not be confused with Villa Auditore in Monteriggioni. Villa Auditore is Ezio's family home and headquarters in Assassin's Creed II. Brotherhood changes the main base to Rome's Tiber Island, reflecting Ezio's wider campaign against the Borgia-controlled city.
