The highly identifiable Santa Marta lighthouse rises on what was originally Cascais’s southernmost point (the marina now extends beyond the point). Built in 1868 on the ruins of a 17th-century fort, the lighthouse only became operational after the site was decommissioned as a military installation.
Santa Marta’s characteristic blue and white striped tower rises 8 metres (25ft) tall and still guards the Tagus’ mouth. Until 1981, it was continually manned by lighthouse keepers; however, the light is now automated.
The lighthouse and fort currently contain a small museum that chronicles the history of the location as well as the evolution of the optical instruments employed in Portugal’s lighthouses. There are interactive light and optic collections, as well as multimedia displays. The job of a lighthouse keeper is another topic addressed by the museum.
A lovely small cafe is located on the fort’s terrace, overlooking the Cascais cliffs.
