About Trincheira Lighthouse

Also known as: Trincheira (Pontal da Barra, Itapoá)

The Trincheira lighthouse, built in 1948, is an octagonal masonry tower standing 8 meters tall. It displays red and white horizontal bands and guides vessels with a red light showing a single flash every six seconds. The focal height of the light is 9 meters, with a geographic range of 10 nautical miles. The lighthouse is located on the north side of the Rio São Francisco do Sul estuary in Itapoá. This structure has faced threats from beach erosion, prompting the placement of stones and, around 2016, the construction of a sea wall and protective fill.

Why it matters: The lighthouse ensures safe passage into the Rio São Francisco do Sul estuary, serving local fishing and recreational boats.
