Santa Marta Lighthouse, Maritime lighthouse in Laguna, Brazil

The Santa Marta Lighthouse is a square stone tower with a lantern and gallery, its walls two metres thick, rising 29 metres on a promontory 45 metres above the sea at Cabo de Santa Marta in Laguna. It stands among single-storey keepers' houses and technical buildings, at the easternmost point of the region.

The lighthouse was built in 1891 as Brazil expanded and modernized its sea routes. Since then, it has guided ships safely through the challenging waters off the Santa Catarina coast.

The lighthouse is owned by the Brazilian Navy and run by the Centro de Sinalização Náutica e Reparos Almirante Moraes Rego, under the Directorate of Hydrography and Navigation. Its French-made Fresnel lens, built by Barbier, Bénard et Turenne, is the only hyper-radiant lens of its kind in Brazil. The tower rises among single-storey keepers' houses and technical buildings.

Access to the lighthouse is free and open to the public; a virtual tour is also available. The tower rises 29 metres on a promontory 45 metres above sea level, so the climb is on foot. The lighthouse stands among single-storey keepers' houses and technical buildings.

The lighthouse's Fresnel lens, made by the French firm Barbier, Bénard et Turenne, has a focal length of 1,330 mm and is the only hyper-radiant lens of its kind in Brazil; only a few remain in service worldwide. The tower also carries a Racon radar that transmits the letter Z in Morse code and a DGPS station.
