Lighthouse of Saint-Valery-en-Caux, Maritime lighthouse in Saint-Valery-en-Caux, France.

The Lighthouse of Saint-Valery-en-Caux is a white cylindrical structure with a green lantern gallery positioned at the end of the western jetty, standing approximately 12 meters tall. It functions as part of a navigation system together with an older cast iron beacon across the harbor.

The structure was built in 1882 to guide ships and was later electrified in 1958, shifting from manual to automated operation. This modernization improved reliability and adjusted the navigation system to changing maritime needs.

The tower's green lantern and the red light on the east jetty form a pair of harbour marks: the west jetty light is white, the east one red, so boats entering the port can tell the two jetties apart. The red light is a cast iron candelabrum from 1960, replacing an earlier sheet-metal beacon of 1914 destroyed in 1944.

The structure sits at the end of the western jetty and is easily accessible from the harbor area, offering good views of the port. Visitors should be cautious during windy or wet weather, as exposed areas near the water can become slippery.

The red light on the east jetty is a cast iron candelabrum from 1960, not the 1857 date sometimes given. The west jetty's white tower and this red light mark the two sides of the harbour entrance for boats entering Saint-Valery-en-Caux.
