Istanbul, Yoros Castle atop the hill at Anadolu Kavagi
Atop the hill at Anadolu Kavagi, on a site of an ancient temple
dedicated to Zeus, the Byzantines built a castle,(shown here
in the photo) Yoros Castle; on the opposite side on the hill
at Rumeli Kavagi, 100 years earlier Manuel I Comnenus had built
Imros Castle for defense and customs dues for passing ships
purposes. Both castles have been taken successively by the Genoese
and Ottomans, in the 14th and 15th c. respectively.
The remains of the castles have been used for long as natural
setting for romantic pictures and wedding ceremonies.
