Phare de Lanvaon

The Lanvaon lighthouse was put into service in 1868, in the commune of Plouguerneau, in Finistère. It was designed by the engineer Alfred Cahen, who also drew the plans for the Morlaix viaduct. It succeeds to a lantern, too little visible, installed on August 15, 1845 in a small hut fitted in the bell tower of the church of Plouguerneau. This light was fixed and white, and often invisible. Moreover, the bad weather and the fog reduced its range. It was built by the Martin company of Landerneau. In the 1980s, engineers decided to paint the top of the tower orange, then red to make it more visible by day from the sea.

The lighthouse is a square tower, inhabited until 1991, adjoining technical premises, in masonry and stone angles.
