The Assassin Brotherhood's headquarters in Assassin's Creed Revelations is the Galata Den. It is located in Constantinople, the game's principal city, and serves as a base for Ezio Auditore's activities.
Revelations divides Constantinople into districts and includes a system of Assassin dens that can be defended from Templar attacks. The Galata Den is the central headquarters, while other dens help Ezio extend Assassin influence across the city. The game also includes Cappadocia as a separate major location.
The name can be confused with other series bases. Villa Auditore is Ezio's family estate in Monteriggioni, and Davenport Homestead is associated with Connor in Assassin's Creed III. Revelations was released in 2011 and concludes Ezio's main story while also returning to Altaïr Ibn-La'Ahad's history.
