Copacabana is a bairro (neighbourhood) located in the South Zone of the city of Rio de Janeiro, Brazil. It is known for its 4 km balneario beach, which is one of the most famous in the world.
Copacabana beach stretches from Posto Dois (lifeguard watchtower Two) to Posto Seis (lifeguard watchtower Six). Leme is at Posto Um (lifeguard watchtower One). There are historic forts at both ends of Copacabana beach; Fort Copacabana, built in 1914, is at the south end by Posto Seis and Fort Duque de Caxias, built in 1779, at the north end. One curiosity is that the lifeguard watchtower of Posto Seis never existed.
