Establishment work began in 1892 and the grand opening ball was held in 1895.
Alexandre Vallaury, a
French-
Ottoman architect living in the city designed the hotel in a blend of neo-classical,
Art Nouveau and oriental styles. Vallaury undertook a number of other projects in
Constantinople (now Istanbul), including the
Ottoman Bank Headquarters and the
Imperial Museum. The hotel was the first building in the
Ottoman Empire to be powered by electricity, other than the
imperial palaces. It was also the only address in the city to provide hot running water for its guests and was home to the first electric elevator in Constantinople. It was also the second electric elevator in Europe. One of the hotel's first owners were the
Ottoman Armenian Esayan family. The hotel was damaged in a bomb attack on 24 March 1941 which killed five people including four Turkish nationals and a British diplomatic worker and injured 30 others. Two hotel porters were among the victims killed. The bombs originated in the luggage room, in suitcases brought by staff of the British Legation in
Sofia led by Ambassador
George William Rendel, who survived the attack, when they moved to Istanbul following the severing of diplomatic relations with Bulgaria during World War II. ==Architecture and renovation==
