Adile Sultan Palace is the former royal residence of Ottoman princess Adile Sultan. It was donated to the state by Adile Sultan to be used as a school building for the Kandilli Anatolian High School for Girls and is today a cultural center. It is located in the Kandilli neighbourhood of Istanbul, Turkey.
The palace was built for the Ottoman princess Adile Sultan (1826–1899), the daughter of Sultan Mahmud II (1789–1839) and the sister of the Sultans Abdülmecid I (1823–1861) and Abdülaziz (1830–1876), and designed by the court architect Sarkis Balyan. It was erected on the same place of a kiosk, which was presented to her by Sultan Abdülmecid in 1856. The palace was commissioned by Sultan Abdülaziz and built by Balyan in 1861. It stands at one of the most prominent places in Istanbul, upon a hill, which is a headland in the middle of Bosphorus on the Asian shore. This location enables a panoramic view of Bosphorus, reaching from the Sea of Marmara to the Black Sea, seen out of all the rooms in three sides of the building. The palace with has 55 rooms and is on a ground of 17,000 m².
Adile Sultan, a great and the only Turkish royal female poet having a Diwan, lived here until the death of her husband Mehmet Ali Pasha in 1868. She donated her residence to the state to be used as a high school for girls after her death in February 1899. Before it was used as determined, the palace came a short while under the control of Ministry of War during World War I.
