​Very close to the mouth of the Tagus, there was once a hermitage called S. Gião, from which the name of the current fortress derives, whose construction apparently began in 1556 at the end of the reign of King João III.

The fortress was the scene of two surrenders: delivered during the Filipino domination by D. Tristão Vaz da Veiga in agreement with the enemy in 1580 and in 1640 by an officer of Philip III, D. Fernando de La Cueva in exchange for a substantial reward. It was a prison – military and political – from the reign of the Filipes until the reign of D. Miguel.

The Pombaline charter of February 1, 1758 ordered the construction of the lighthouse of S. Julião, among others. Through a document from the time, it is thought that there had already been a lighthouse in S. Julião and that it was destroyed by the earthquake of 1755.

The illuminating system installed in 1775, which was not very efficient, consisted of an Argand lamp set with a parabolic reflector.

Between 1848 and 1865 the lighthouse was modernized, with a 4th order Fresnel lenticular device installed on the latter date (it was the fourth lighthouse on our coast to receive this type of device), producing fixed white light, powered by gas distilled from wood.

From 1880 on, lighting began to be obtained by the incandescence of gas obtained from petroleum.

In 1916 a horn sound signal was installed. From 1916 to 1918 the lighthouse was turned off for military reasons, due to the First World War.

The light from the lighthouse, which was fixed, white, in 1933 became red occultation due to the resolution of the beaconing conference, held in Lisbon, which banned the fixed lights of beacons on the margins of important cities or towns. On the same date, the lighthouse was connected to the public distribution grid.

Integrated in the remote control network of the approaches to the port of Lisbon, it was automated in 1980, being remotely controlled from the Headquarters of Faros.
