The Beylerbeyi Palace is an Imperial Ottoman summer residence and a place to entertain visiting heads of state built in the 1860s. Empress Eugénie of France visited Beylerbeyi on her way to the opening of the Suez Canal in 1869 and had her face slapped by the sultan's mother for daring to enter the palace on the arm of Abdülaziz. Other regal visitors to the palace included the Duke and Duchess of Windsor. The palace was the last place of captivity of the deposed sultan Abdulhamid II from 1912 until his death there in 1918.
