Abrolhos Lighthouse, Lighthouse on Santa Bárbara Island, Bahia, Brazil.

The Abrolhos Lighthouse is a 22-meter cylindrical cast-iron tower with a double gallery, painted in narrow horizontal black and white bands, standing on Santa Bárbara Island in the Abrolhos Archipelago. The tower was prefabricated in France and is topped by a meso-radiant Fresnel lens made by Barbier & Bernard.

The cast-iron tower was prefabricated in France and erected on the summit of Santa Bárbara Island, the largest of the Abrolhos Archipelago, where it began operating in 1862. It is owned by the Brazilian Navy and managed by the Centro de Sinalização Náutica e Reparos Almirante Moraes Rego (CAMR), within the Diretoria de Hidrografia e Navegação. Its Fresnel lens came from the French firm Barbier, Bénard et Turenne.

The lighthouse represents a significant piece of Brazilian maritime heritage, featuring one of only two meso-radiant Fresnel lenses manufactured by Barbier & Bernard existing in the country.

Visitors can access the lighthouse through prior authorization from the 2nd Naval District command, with boat trips typically departing from coastal towns in southern Bahia.

The lighthouse carries one of only two meso-radiant Fresnel lenses known to have been made by Barbier & Bernard; the other is at the Rasa Island Lighthouse in Rio de Janeiro state. It also has a Racon radar sending the letter Q in Morse code, with a range of 25 nautical miles.
