Triagoz lighthouse, Stone lighthouse on the Guen-Arms rock of Triagoz archipelago in Perros-Guirec, France.
The square tower rises 15 meters from its base, constructed with pink granite blocks sourced from the quarries of Ploumanac'h near the coast.
Engineers Dujardin and Pelau supervised the construction of this maritime safety structure between 1861 and 1864 to guide vessels through dangerous waters.
The lighthouse earned its status as a monument historique classé in 2017, joining the collection of protected maritime structures along French coasts.
The lighthouse operates with a characteristic light pattern of Oc(2) WR 6s at coordinates 48.871389 latitude and -3.646389 longitude for maritime navigation.
The original lantern of this automated structure now resides in a courtyard in Lézardrieux, while the tower maintains its semicircular projection toward the coast.
