Which city does Assassin's Creed Revelations primarily depict?

Constantinople is the primary city depicted in Assassin's Creed Revelations.

The game follows Ezio Auditore in the early sixteenth century as he travels to the capital of the Byzantine Empire. The historical setting includes Constantinople's districts, landmarks, and political tensions, while the story also returns to the life and legacy of Altaïr Ibn-La'Ahad.

The city is divided into areas associated with factions such as the Assassins, Templars, and Byzantine forces. Ezio uses a hookblade, expands the Assassin network, and explores underground areas known as the Cappadocia region. The game also includes a modern-day storyline involving Desmond Miles.

Revelations was released in 2011 and concludes Ezio's main trilogy. Constantinople is the historical city's conventional English name in the period represented by the game; Istanbul became the city's official name internationally in the twentieth century. This historical naming difference can cause confusion when identifying the setting.
