Copacabana beach, located at the Atlantic shore, 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.Hotels, restaurants, bars, nightclubs and residential buildings dot the promenade facing Avenida Atlântica. On Sundays and holidays, one side of Avenida Atlântica is closed to cars, giving residents and tourists more space for activities along the beach.
