Which real historical city is recreated in Assassin's Creed Revelations?

Constantinople is the real historical city recreated in Assassin's Creed Revelations. The game places Ezio Auditore in the Ottoman capital during the early 16th century, where he searches for Altaïr's hidden legacy and becomes involved in local political struggles.

The city is divided into districts inspired by historical Constantinople, including Constantinople proper and Galata. The game also features the nearby Cappadocia region. Ottoman prince Suleiman appears in the story as a young historical figure, while other real figures and fictional characters share the setting.

Constantinople was the name commonly used for the city now known as Istanbul during the period portrayed by the game. It was the capital of the Byzantine Empire until 1453 and became the Ottoman capital after the Ottoman conquest. Revelations therefore uses a city at the meeting point of Byzantine and Ottoman history, rather than setting Ezio's final adventure in Renaissance Italy.
