Rio de Janeiro’s Sambadrome opened in 1984.
Before the venue was built, Rio’s major samba-school parades used temporary structures and changing street arrangements. A permanent complex gave the competition a defined route, fixed spectator facilities and a more reliable setting for judging and television coverage.
The Sambadrome was constructed on Avenida Marquês de Sapucaí and designed by Oscar Niemeyer. It is officially known as Passarela Professor Darcy Ribeiro, after the Brazilian educator and politician. The first carnival season held there was in 1984, making that year a turning point in the organization of Rio’s main parade.
The date is sometimes confused with later expansions or renovations. The venue has been modified over time, including work connected with major international events, but its opening year remains 1984. The Sambadrome is also not the whole of Rio carnival: street blocos, balls and neighborhood events continue across the city outside the purpose-built parade avenue.
