Riocentro, Exhibition and convention center in Barra da Tijuca, Brazil

Riocentro is a convention and exhibition complex in Barra Olímpica, Rio de Janeiro, made up of five interconnected pavilions covering 100,000 square metres within a 571,000-square-metre park. Its pavilions seat between 2,000 and 4,500 people, and the grounds include parking for about 7,000 cars and 60 buses.

The center opened in 1977 and gained international attention when hosting the United Nations Earth Summit in 1992 focused on environmental protection. That event established the venue as a significant gathering place for major international conferences.

Riocentro regularly hosts the Bienal do Livro do Rio de Janeiro, the city's book biennial, where Brazilian publishers present their catalogues and authors meet readers. The name Riocentro simply combines Rio with centro, marking it as the city's main events complex. Its five interconnected pavilions also serve fairs, congresses and sports events.

Riocentro sits in Barra Olímpica, in western Rio de Janeiro, on a 571,000-square-metre park with parking for about 7,000 cars and 60 buses. Its five interconnected pavilions total 100,000 square metres, so allow time to walk between them during multi-hall events. The complex is reached from the Barra da Tijuca area, and the pavilions are numbered, which helps orientation.

One of the pavilions served as a boxing venue during the 2016 Summer Olympics, transforming to accommodate thousands of spectators for the sport. The space was specially adapted to meet the demands of hosting this international athletic competition.
