The Galata headquarters was a building located in the northern tip of Constantinople's Galata District, and served as a base for the Turkish Assassins within the city. During his time in the city in 1511 and 1512, Ezio Auditore utilized the building and its amenities. Accessible from both a small courtyard and Constantinople's tunnel system, the headquarters acted as an ideal location for the Assassins to continue operations during the Byzantine attempt at reoccupation.
