One of the most dangerous parts of the Costa da Morte is dominated by the oldest electric lighthouse in Spain, first lit on January 15th, 1896. In 1933 it was declared as National Landscape Interest because of its beauty. Inside you will find a room exhibiting all the original machinery. Not far away, at Punta do Boi, sank, in 1890, a Royal navy vessel, the HMS Serpent. There were 172 dead men and 3 survivors. The dead were buried at the beach and today this is known as the Englishmen cemetery. Located in a stunning area, A Enseada do Trece stands out for its 492-foot climbing sand dune, one of the highest in Europe.
