Yeşilköy Feneri

[6] [7] Built in 1856, it was initially called Ayostefanos Feneri (Hagios Stefanos Lighthouse) after the suburb's former name.

[3][5] The lighthouse was commissioned by the Ottoman sultan Abdülmecid I (reigned 1839–1861) in order to provide safe navigation around the shallow waters before the Yeşilköy Point for ships plying the northwestern coast of the Sea of Marmara towards Istanbul.

The lighthouse's lantern has a 500mm catadioptric cylindrical lens and a 500 W light source that flashes every 10 seconds in group.

[8] It is maintained by the Coastal Safety Authority (Turkish: Kıyı Emniyeti Genel Müdürlüğü) of the Ministry of Transport and Communication.

[5] The outbuilding of the lighthouse was converted into a fish and seafood restaurant, which can host 100 guests in the main hall and 40 people in the conservatory.
