Cabo Branco Lighthouse is located on a cliff on the beach of Cabo Branco. Situated about 800 metres north of Ponta do Seixas, the easternmost point of mainland Brazil. It is one of the most important and visited postcards of Paraíba's Capital.
With a triangular Tower in concrete, three wing-shaped pointed projections to 3.5 m from the ground, the Lighthouse is painted white with a black horizontal band just above the wings. For decades, long before the city of João Pessoa enter sightseeing, Cabo Branco lighthouse was already known by Mark "the easternmost point of the Americas".
