Porto Seguro Lighthouse, Maritime lighthouse in Porto Seguro, Brazil

The Porto Seguro Lighthouse is a square masonry tower 12 m tall with a gallery, painted entirely white, standing on a slope above the BR-367 coastal road about 1.5 km north of Porto Seguro. It marks the entrance to the channel sheltered by the reef along the coast and shows two white flashes followed by a red one every 30 seconds.

The first lighthouse was inaugurated on 10 July 1907, in an extraordinary session of the Porto Seguro municipal council held at the Casa de Câmara e Cadeia, with colonel-intendant José Ribeiro Coelho, captain-lieutenant Heráclito Graça Aranha and engineer Alfredo Setúbal present. It stood on a 60-by-60-metre plot donated by the municipality to the federal government. In 1947 the iron structure with an external staircase was replaced by the present tower, built under Mário Seixas Santos with materials shipped from Salvador on the vessel Ilhéus.

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 light pattern, two white flashes then one red every 30 seconds, is a fixed part of local navigation. The tower is listed as Brazilian historic heritage.

The lighthouse stands on a slope above the coastal road BR-367, about 1.5 km north of Porto Seguro, in the Cidade Histórica. Its focal plane is 57 m above sea level and the light reaches 21 nautical miles. The tower is 12 m tall, so the climb is short; the site is reached by road from the town.
