In Assassin's Creed Revelations, which city does Ezio visit to uncover Altaïr's secrets?

In Assassin's Creed Revelations, Ezio visits Constantinople to uncover Altaïr's secrets. The city, known today as Istanbul, is the main setting for Ezio’s search for the keys to Altaïr’s library in Masyaf.

The game is set in the early sixteenth century, primarily in Constantinople during the reign of Sultan Bayezid II. Ezio arrives there while pursuing the five Masyaf keys, which contain memories from Altaïr’s later life. His investigation brings him into contact with local Assassins, Ottoman princes, and the Byzantine Templars.

Constantinople was the capital of the Byzantine Empire and became the Ottoman capital after its conquest in 1453. Revelations uses the city’s districts, markets, waterways, and monumental architecture as the foundation for its movement and missions.

Jerusalem and Damascus are important cities in the original Assassin’s Creed, and Alexandria appears elsewhere in the series. They are not Ezio’s principal destination in Revelations.
