Istanbul, the largest city in Turkey, was the capital of the Byzantine and Ottoman empires. The Bosphorus straits divides the city into a part that sits on the European continent, and a larger part on the continent of Asia. The militarily and economically strategic position of the city, on the western portion of the Silk Road, and on the shipping route between the Aegean and Black Seas, has kept it cosmopolitan and prosperous since its foundation 660 BCE, when it was called Byzantium. In 330 it became Constantinople, the capital of the Roman Empire, named for Emperor Constantine the Great. The Ottomans conquered the city in 1453/857 AH and renamed the city Istanbul. It served as their capital until Ankara became the capital of the modern nation of Turkey.
A multipurpose event space in the Ortaköy district of Istanbul, built inside the ruins of a brick palace that was built in 1875 by architect Sarkis Balyan for Esma Sultan, sister of Sultan Abdülaziz.
The incorporated structure is built out of steel and glass within the original brick exterior. The glass box is tethered to the walls with suspension rods, which ensure that the structures remain equidistant from each other and are able to withstand bad weather and earthquakes. The building is set on several levels and includes a bar, a restaurant, and an event hall.
