The strategic position that the fort of S. Marta had for military purposes, it also had for navigation, and in its report the Inspection of the Lighthouses of the Kingdom in 1864, advocated the installation of a light there.

The Fort of S. Marta came under the dependence of the Service of Lighthouses on November 8, 1867.

In 1868, a small tower was built, serving as a sign for the day and receiving a red catoptric headlight, functioning only as a direction light that turned on for the first time on the night of March 1st.

A script from 1897 describes the structure of the lighthouse and the dispositions adopted in terms of optics: «Pharol de Santa Martha – close to Ponta de Salmodo, in the southeast angle of the old fort of S. Martha, there is the square tower of the lighthouse, painted in white, with a blue stripe at mid-height. The beacon has a fixed red light, given by a dioptric device and reinforced in the direction of the alignment of the corridor or northern channel, by a catoptric device (...)».

These lights were provisionally mounted in one of the windows of the tower, one constituting the harbor light and the other giving the Santa Marta – Guia line.

In 1908 these lights were replaced by a 5th order catadioptric device, which is still there today, with fixed light.

In 1936, the height of the tower was increased by 8 meters, due to the constructions that were being carried out in the vicinity and which made it difficult for navigation to navigate from the north bar.

Classified as a property of public interest, it was mentioned twice in the Diário da República.

In 1949, a sound signal was installed, and the lighthouse was connected to the public electricity grid in 1953. It changed from a fixed light to a red occultation light.

Inserted in the automation plan of the Tagus bar, it was automated in 1981, being remotely controlled from the Faros Management Central.

In 2000, a protocol was signed between the Municipality of Cascais and the Navy, for the transfer of the lighthouse's dwellings to later operate the lighthouse museum of S. Marta.

In July 2007, the Lighthouse Museum of S. Marta was opened to the public, equipped with pieces from the assets of the Museum of the Directorate of Lighthouses.
