Adviser Almeida de Ávila already proposed, in 1891, that a beacon be installed visible in regular weather from 10 to 12 miles at Ponta da Serreta.

The Serreta Lighthouse came into operation on November 4, 1908. It is located at Ponta do Queimado or Ponta da Serreta. It had a tower 11 meters high and 96 meters high. Initially, it was equipped with a 5th order catadioptric apparatus, the light source being a constant level lamp. The rotation of the optics was produced by the watchmaking machine.

The optical apparatus was replaced in 1935 by another of the 4th order.

The light source in 1947 became incandescence by oil vapor.

The lighthouse was electrified in 1958 using generator sets, with the light source becoming a 3000W electric incandescent lamp.

Due to the bad condition it was in, the optics were replaced by another of the 4th order, which had been removed from the Sagres lighthouse.

The lighthouse was destroyed by the earthquake on January 1, 1980, which occurred at 3:46 pm. Four prefabricated houses were temporarily installed to accommodate the lighthouse keepers, almost a year later. During this period of time, the staff lived in the lighthouse's facilities (garages, warehouses, etc.), starting yet another story of sacrifice, of which the history of lighthouses is fertile. As for the tower, further thought was given to promoting its consolidation, but in 1982 that project was abandoned because it was too expensive. As the structure that had been removed from Cacilhas in the 1970s existed in Lisbon, it was decided to install this structure.

A 6th order lantern was provisionally installed in 1983, while the lighthouse structure was being assembled.

The provisional lighthouse was deactivated in 1986, the eclipser (EDOLD) was transferred to the lighthouse and a new 5th order optical device was fitted, with the characteristic and sector of visibility being altered. The tower was 15 meters high.

In 1987 the lighthouse was remodeled and automated with the SIRIUS system, starting to work using solar energy with the installation of photovoltaic panels.

It was left as a reserve with a generating set.

In the year 2000, the SIRIUS system was replaced by the ELCO – 12 system.

In 2001 the Almada City Council showed interest in the lighthouse structure returning to Cacilhas.

In June 2004, the lighthouse structure was replaced by fiber modules, making it 14 meters high.
