Galata headquarters

The Galata headquarters was a building located in the nothern tip of Constantinople's Galata district, and served as a base for the Turkish Assassins within the city. Between 1511-1512, during his time in the city, Ezio Auditore Da Firenze utilized the building and it's amenities. Accessible from both a small courtyard and Constantinople's tunnel system, the headquarters acted as an idyllic location for the Assassin's to continue operations during the Byzantine attempt at re-occupation.

Function
Function-wise, it was similar to both the Villa Auditore and the Tiber Island headquarters, albeit with some additional features. It's rooms included a large cavernous entrance way leading to a Main hall, a bomb crafting room - unlike it's Italian counterparts, an Armory divided into two, like that of the Villa Auditore, one room displayed acquired weaponry and the other held armor sets. In place of a painting gallery, the Galata headquarters hosted a library, where books purchased from shops and recovered by deciphering the Polo Symbols were displayed.

The appropriate guild's crest appeared on walls within the library upon completion of the corresponding Guild Challenges, and are labeled to have been awarded to Ezio by the attributed factions in tribute to his skill.

Any recruits of the Order can often be seen milling around or speaking to each other in the rooms of the headquarters when not out on missions.

The banners displayed throughout the base are unlike that seen at the Villa Auditore or Tiber Island, instead the Ottoman variant of the Assassin's crest occupies the building.

Entrances
There were two entrances to the Galata headquarters: the street entrance, and a tunnel entrance.

Street entrance: The street entrance was located at the eastern side of the building, inside a small courtyard.

Tunnel entrance: The tunnel entrance was located to the west of the main hall but could be accessed through any of the tunnel entrances scattered throughout the city.

Main Hall
The main hall was the focal point of the headquarters' interior. Introduced through a large entrance way, it housed entrances to all the other rooms, held a guild management area and a guild ranking board.

Bomb Crafting room
The bomb crafting room was located to the south of the entrance walkway. It was separated from the rest of the headquarters, presumably in an attempt to limit damage or injury caused by accidents. The room contained crafting supplies, a bomb codex and a crafting table.

Library
The library was situated north of the main hall. It held books bought from book shops throughout Constantinople, texts purchased in Cappadocia and literature recovered by deciphering the Polo Symbols. Guild crests awarded to Ezio were displayed on the walls of the library. A desk close to the entrance was dedicated to Ezio during his stay in the city. Here he wrote letters to his sister Claudia and also studied Masyaf keys he acquired.
