Farol da Gibalta

The Gibalta Lighthouse, also known as Farol da Gibalta, is located in Oeiras, Portugal, approximately 10 kilometers west of Lisbon's center. The lighthouse was originally built in 1914, but it was rebuilt in 1954 after a landslide destroyed the old light and caused the death of ten people on a passing train. The current lighthouse is a white cylindrical tower with a dome and red veins, standing at a height of 21 meters.

The lighthouse has a fifth-order Fresnel lens and a range of 21 nautical miles, with a characteristic of occulting red every 3 seconds. The light is supplied by a red fluorescent lamp. The lighthouse was automated in 1981 and has been lit all year round since 1997. Prior to its automation, the lighthouse was only lit from October to March between 1987 and 1997.

The Gibalta Lighthouse has an interesting history, with its predecessors dating back to 1878 and 1879. The original lighthouses used catoptric devices with parabolic reflectors and Argand lamps. The current lighthouse began operation on February 10, 1954, and has since undergone several updates, including the installation of a new remote control system in 2000. The lighthouse plays an important role in guiding ships into Lisbon's port and has become a notable landmark in the area.
