It was thought as a fourth-order lighthouse to indicate and guide the entrance to the Arousa estuary.
In 1851 the engineer Celedonio Uribe is commissioned to design a very small building located at Punta Besugueira, the most outgoing part to the south of the island.
It starts operating in 1853 with a range of 10 miles.
In 1902 a new lighthouse was designed by Antonio Herbella but his project was rejected and commissioned to Ramón Martínez de Campos in 1906, entering into operation in December 1921. Publications of the time define it as one of the most modern and best equipped lighthouses of Spain.
At present it is electrified and uses voltaic energy. Its light has a range of 21 miles.
