Anadolu Feneri is a historical lighthouse still in use, which is located on the Asian side of Bosphorus' Black Sea entrance in Istanbul, Turkey.
It is across from the lighthouse Rumeli Feneri, which is on the European side of the strait at a distance of 2 nmi (3.7 km; 2.3 mi).
[2][3] François Baron de Tott, a French engineer and military officer of Hungarian origin, who lived some years in Istanbul, reported on the existence of a lighthouse at this location in 1755.
[2] Today, it is maintained by the Coastal Safety Authority (Turkish: Kıyı Emniyeti Genel Müdürlüğü) of the Ministry of Transport and Communication.
The lighthouse's lantern flashes every 20 seconds and its light is visible at a range of 20 nmi (37 km; 23 mi).
