Photographer's Note

The Sile a historical lighthouse still in use, is located on the western Black Sea coast in the northeast town Sile of Istanbul Province, Turky.

Commissioned by the Ottoman sultan Abdulmecid I (reigned 1839 1861), it was consecrated in 1859 by French engineers. In 1860 the lighthouse went into service.

The masonry lighthouse is built on a cliffy point at Cape Sile about 1 km northeast of the town. The 19 m (62 ft) tower with a gallery around the lantern room has the form of an octagonal prism. A masonry one-story keeper's house is attached to it. The lighthouse is painted white with narrow black horizontal bands.

Initially, the lighthouse was lit by kerosene, however the light source was later replaced by Dalen light using carbide (acetylene gas). Since 1968 it runs on electricity. The lighthouse's lantern has eight 925 mm catadioptric cylindrical lenses and a 1,000 W light source. At a focal height of 60 m (200 ft) it flashes white for 1.5 sec every 15 seconds, which is visible at a range of 20 nm (37 km).
