In Assassin's Creed: Brotherhood, what is the name of Ezio Auditore's Roman hideout?

In Assassin's Creed: Brotherhood, Ezio Auditore's Roman hideout is Isola Tiberina.

Isola Tiberina is a small island in the Tiber River, and Brotherhood uses it as the headquarters of the Assassin network in Rome. Ezio can return there to manage recruits, access key services, and receive information connected with the campaign against the Borgia family. Its island setting makes it visually distinct from the surrounding Roman districts.

Players sometimes confuse the hideout with Monteriggioni's Villa Auditore, which is Ezio's family home and the central base in Assassin's Creed II. They may also associate Ezio with Castel Sant'Angelo, but that fortress is an important location in Rome rather than the Assassin headquarters.

The real Isola Tiberina has a long religious and medical history. Its shape was traditionally compared with a ship, and the island has been associated with healing since antiquity. Brotherhood turns this real landmark into a secure operational base for a fictional Renaissance Brotherhood.
