This lighthouse has a spectacular site, even by the standards of this coast: it seems almost suspended above the sea. It earns its nickname as El Guardián del Vértigo. Bonfires have been lit at this spot for centuries to aid sailors.
At the beginning of XX century the request of the villagers to remode the lighthouse was reflected in a folksong: " El faro de Cudillero lo van a poner más alto, pa que alumbre a San Esteban y no se pierdan los barcos " (The lighthouse of Cudillero is going it to put upper, so that lights to San Esteban and the boats are not lost).
The lighthouse was expanded in 1921 and again in the 1980s as part of the Plan de Señales Marítimas; at that time the tower was heightened with a new lantern and the second gallery.
Located atop a vertical headland to north of Cudillero at the Eastern margin of the port entrance.
