Sines Lighthouse, Maritime navigation point at Cabo de Sines, Portugal

Sines Lighthouse is a white cylindrical tower of 22 metres with a red beacon, flanked by two adjoining buildings. The tower now stands in two parts of different diameters, crowned by an iron balcony around the light at 28 metres, with the lantern's altitude at 56 metres.

The lighthouse began guiding ships in 1880 using oil-powered optical equipment to warn vessels away from the rocky coast. Technical improvements were made throughout the following century to enhance its navigational effectiveness.

The lighthouse's name comes from Cabo de Sines, the cape it marks. Its 1880 second-order optic was later moved to the Santa Marta Lighthouse Museum in Cascais, where the original lantern and optical device are now displayed. The tower can be visited on Wednesdays between 14.00 and 17.00.

The lighthouse sits within an active industrial harbor area, so stick to marked paths and be aware of your surroundings. The best views come from nearby coastal walkways where you can see the entire structure and the coastline beyond.

The 1992-1995 works raised the tower to 28 metres and split it into two sections of different diameter. The original lantern and optical device were removed and are now held at the Santa Marta Lighthouse Museum in Cascais, so the present optic is not the one installed in 1880.
