Çiragan Palace , a former Ottoman palace, is now a five-star hotel in the Kempinski Hotels chain. It is located on the European shore of the Bosporus, between Besiktas and Ortaköy in Istanbul, Turkey.The palace, built by Sultan Abdülâziz, was designed by the palace architect  Balyan and constructed by his sons Sarkis and Hagop Balyan between 1863 and 1867, during a period in which all Ottoman sultans built their own palaces rather than using those of their ancestors; Çiragan Palace is the last example of this tradition. The inner walls and the roof were made of wood, the outer walls of colorful marble. A beautiful marble bridge connects the palace to the Yildiz Palace on the hill behind. A very high garden wall protects the palace from the outer world.
