In Assassin's Creed Revelations, Ezio visits Constantinople to investigate Altaïr's legacy.
Constantinople, the capital of the Byzantine Empire, is the principal setting for Ezio's final major adventure. He arrives while seeking keys connected to Altaïr Ibn-La'Ahad's memories and the Masyaf fortress. In the city, Ezio becomes involved with the local Assassins and opposes Byzantine forces led by Manuel Palaiologos.
The game's historical Constantinople is the city now commonly called Istanbul. The story uses districts on both sides of the Golden Horn and includes landmarks such as Hagia Sophia and the Galata Tower. Jerusalem is central to the original Assassin's Creed, while Florence is strongly associated with Assassin's Creed II, making them common but incorrect alternatives here.
