History

The 1883 Plano Geral de Alumiamento, proposed the construction of a fourth-order lighthouse, that would flash each minute and have a range.
On 11 November 1902, the Comissão dos Faróis e Balizas proposed alterations to the General Plan approved in 1883, in which the lighthouse became a fifth-order structure, using a three-flash 10-second variable range beacon, with a range of use between for clear, medium and tempestuous weather.
The lighthouse began to function on 26 May 1956, equipped with diotropic fifth-order optics, with a focal distance of, moved by a clockwork mechanism. This first beacon used an incandescent red acetylene light, in two groups with a range.
By 1961, the light became a white beacon, improving its range to
A solar valve system was installed in 1978, that allowed the light to become active or inactive based on the atmospheric conditions.
It was only in 1987 that the lighthouse joined the electrical network on the island. At the same time the optics were substituted by a sixth-order lamp with a focal distance of and the lamp was upgraded to a 50 Watt/12 Volt halogen light, supported by battery and secured by the exterior network.
