Köseleciler Mansion is a small and elegant mansion located on the Asian side of the Bosphorus in the Anadoluhisarı neighborhood of the Beykoz district, right in front of the historical castle (Anadolu Hisarı Castle).
When passing through the Bosphorus by boat, this two-story wooden structure positioned right at the water's edge next to the castle immediately catches the eye. Its simple architecture and harmony with the natural beauties of the Bosphorus leave a nostalgic impact on viewers. Although it may appear modest at first glance, Köseleciler Mansion has become one of the significant parts of the Bosphorus view due to the weight of its location and history.
History
Known to have been built in the 19th century during the Ottoman period, the Köseleciler Mansion is an example of traditional Bosphorus mansion architecture. The structure originally had a unique boathouse (boat house) underneath; however, due to a wharf constructed in front of it in later years, this boathouse's connection to the sea has been severed. The mansion was registered as a cultural heritage site in 1971 and has been protected. Throughout its history, the structure has hosted various families and has recently undergone significant ownership changes. The mansion, once owned by well-known businessman Ali Akkanat in the textile and tourism sectors, was purchased in the early 2010s by Serkan Borançılı, one of the founders of Gittigidiyor.com, for about 10 million US dollars, and extensive renovations were carried out. The renovated Köseleciler Mansion is now used as a private property and, although it can be seen from the outside, it is not open to visitors.
Explore By Yacht
