Calcanhar Lighthouse, Maritime navigation beacon in Touros, Brazil.

Calcanhar Lighthouse is a cylindrical concrete tower that rises 62 meters (203 feet) above the coastline, strengthened by four vertical ribs running up its sides. The structure tapers as it ascends toward the lantern chamber at its top.

The current tower was completed in 1943 and replaced earlier structures from 1912 and 1937 at this strategically important coastal point. The successive reconstructions reflect the site's importance for maritime navigation.

The name Calcanhar refers to the Ponta de Calcanhar beach where the tower stands, near the northern end of the great curve of Cape São Roque. Locals also call it Farol de Touros, and it was originally named Olhos D'Agua. The site keeps a resident keeper and several one-storey keeper's houses beside the tower.

Visitors must climb 277 steps of a spiral staircase to reach the observation platform, then an additional 21 steps to access the lantern area. The ascent is physically demanding and takes place within a narrow, enclosed space.

The lighthouse stands at the "Esquina do Continente", the sharp angle where the Brazilian coast turns. Its light reaches 34.5 nautical miles and its geographic range is 22 miles. The tower also houses a DGPS station for maritime positioning.
