As a port light, a range of fourth-order light was considered sufficient when it was placed in a cove and near the luminous reach of the Tower of Hercules and Cape Prior.
By its rank, also the project carried out, surely by Celedonio de Uribe, provided the construction of great simplicity.
It began to light in March 1854 with a range of 11 nautical miles.
The building underwent several reforms both because of the reduced spaces and the effects of storms, which in 1879 led to the replacement of roof tiles with zinc plates. The most important reforms were carried out in 1882.
Like the building, the lighting system also suffered several modifications until in 1988 it installed the one that maintains at present.
In 1990 suffered a vandalism that not only affected the building but also the optical system so it was off for several months.
Since 1993 the equipment has been modernized and it is monitored to be controlled by computer in the Control Center of the port of Ferrol.
Curiosities, myths and legends
In January 2009, Hurricane Klaus devastated the Galician coast with winds exceeding 150 km per hour. Remember Mercedes, the lighthouse keeper, that the storm ripped the zinc plates that formed the roof of the lighthouse exposing the top floor of the building. She and her partner, along with her cat and her two dogs, took refuge in the bass all night while the sea passed over them.
In spite of the difficulties the lighthouse continued to work because although there was no electricity to supply energy to the lamp, the diesel-powered generators were activated.
