Farol da Ilha da Berlenga/Farol Duque de Bragança

The Farol da Ilha da Berlenga, also known as the Duke of Bragança Lighthouse, is a functioning lighthouse located on the highest point of the granite island of Berlenga Grande, a nature reserve in the Atlantic Ocean, 10 kilometers west of the town of Peniche in Portugal. It was built in 1842, although plans for its construction date back to the 18th century. The lighthouse has a height of 29 meters and features an LED optics system with a range of 27 nautical miles.

The lighthouse has undergone several upgrades and renovations throughout its history. Initially, it was equipped with a catoptric device and oil-fired lamps, but this was later replaced with a new optical device in 1897. The light source was derived from petroleum vapor until 1926, when generators were introduced, allowing a light bulb to be used. In 1985, the lighthouse was automated, and the existing light was replaced with a Pharos Marine PRB-21 sealed beam optic.

Today, the lighthouse is managed by the Directorate for Lighthouses and is an important aid to navigation in the area. The lighthouse and its staff residences have been using solar energy since 2000, and a new high-performance rotary headlamp was introduced, with an estimated range of 20 nautical miles. The lighthouse's use of solar energy earned the Lighthouse Directorate the National Defense and Environment Prize in 2001, recognizing its commitment to good environmental practices.
