Küçüksu Palace or Küçüksu Pavilion, aka Göksu Pavilion, (Turkish: Küçüksu Kasrı) is a summerpalace in Istanbul, Turkey, situated in the Küçüksu neighborhood of Beykoz district on the Asian shore of the Bosphorus between Anadoluhisarı and the Fatih Sultan Mehmet Bridge. The tiny palace was used byOttoman sultans for short stays during country excursions and hunting.
The palace was commissioned by Sultan Abd-ul-Mejid I (1823–1861), and designed by the architectsGarabet Amira Balyan and his son Nigoğayos Balyan in the neo-baroque style. Completed in 1857, the structure took the place of a two storey timber palace built during the reign of Mahmud I (1696–1754) by his Grand Vizier Divittar Mehmed Pasha, then successively used by Selim III (1761–1808) and Mahmud II (1785–1839). ￼
The building consists of two main stories and a basement on a footprint of 15 x 27 m. Unlike other palace gardens with high walls; its garden is surrounded by cast iron railings with one gate at each of the four sides. The basement was appointed with kitchen, larder, and servant's quarters, with the floors above reflecting the design of a traditional Turkish house - four corner rooms surrounding a central hall. The rooms at the waterfront have two fireplaces while the others have one each, all fashioned from colorful Italian marble. The rooms boast crystal chandeliers from Bohemia, with curtains, furniture upholstery, and carpets woven in Hereke. The halls and the rooms exhibit paintings and arts objects; Sechan, stage designer at Vienna State Opera, was charged for the decoration of the interior.
During the reign of Sultan Abd-ul-Aziz (1830–1876), more elaborate decoration was added to the façade; some of the original garden outbuildings were demolished at that time. In the beginning of the Republican era, the site was used as a state guesthouse for some years. Since a thorough restoration in 1944, the palace has been open to the public as a museum.
The palace appeared in the James Bond film "The World Is Not Enough" as the mansion of a woman in Baku. The palace also appeared in popular Bollywood film Ek Tha Tiger.
