Princes' Islands
Marmara Region
The Princes' Islands, also known as Prens Adaları or the Princes' Archipelago, are a group of nine islands located in the Sea of Marmara near Istanbul, Turkey. With a total land area of 11 km², they form the district of Adalar within Istanbul Province and have a permanent population of around 16,690 as of 2022. Historically, the islands served as places of exile for Byzantine princes and Ottoman royalty, which is reflected in their name. The largest islands-Büyükada, Heybeliada, Burgazada, and Kınalıada-feature well-preserved Victorian-era cottages and mansions, a legacy of their popularity as a summer resort for Istanbul's wealthy during the 19th century. The islands are unique for their multicultural heritage, once home to significant Greek, Armenian, and other minority communities. Notable is the Halki Theological School on Heybeliada, an important Eastern Orthodox seminary founded in 1844, situated atop the Hill of Hope. The islands' geography includes several hills and a lack of freshwater sources, and they are renowned for their peaceful, car-free environment where transportation is largely by horse-drawn carriage and bicycle. Easily accessible by ferry from Istanbul, the Princes' Islands offer visitors a tranquil escape with rich cultural and historical significance.
