Gibalta Lighthouse, Maritime navigation aid in Oeiras e São Julião da Barra, Portugal.
Gibalta Lighthouse is a navigational aid on the Portuguese coast near the mouth of the Tagus River, featuring a white tower with a red dome. The structure rises 21 meters tall and was specifically designed to guide ships through this busy harbor area.
The original structure was destroyed by a landslide before 1952. The current lighthouse was rebuilt in 1954 approximately 30 meters from the original site and has served maritime safety ever since.
The lighthouse stands as a familiar marker for ships approaching Lisbon's harbor, and locals recognize it as part of their port landscape. Its location at the mouth of the Tagus connects it closely to the daily maritime traffic of this busy region.
The structure operates fully automatically and emits a red light signal every three seconds. The light beam can reach ships from up to 21 nautical miles away and is ideally positioned for navigation in this coastal area.
The exterior of the lighthouse underwent a major transformation in 1973 when it was repainted from gray to white with red dome ribs. This color scheme makes it today a visual marker that stands out clearly against the sky.
