. The site of the Barra Olympic Park was formerly occupied by the
Autódromo Internacional Nelson Piquet, also known as
Jacarepaguá. It was a former
Formula One circuit that hosted the
Brazilian Grand Prix on a number of occasions throughout the 1980s, before the Grand Prix went back to its original home at the
Autódromo José Carlos Pace, Interlagos, in 1990. Jacarepaguá was partly demolished to make way for the City of Sports Complex, a cluster of three venues constructed for the
2007 Pan American Games, held in Rio de Janeiro. The venues consisted the
Maria Lenk Aquatic Center, which held
diving,
swimming and
synchronized swimming events, the
Rio Olympic Arena, which held
basketball and
artistic gymnastics events, and the
Barra Velodrome, which held
track cycling and
speed roller skating events. Construction of the City of Sports was not without setbacks – the original plan for the complex called for a large-scale entertainment complex, valued at
R$ 500 million and contracted to private firms for construction. These plans, however, fell through, and a smaller-scale plan for the complex was adopted instead. Opposition efforts by preservationists of the Jacarepaguá, the unsuitable soil at the construction site and numerous strike actions by workers delayed the venue's construction, which initially planned to begin in 2005, but was delayed until mid-2006. thus the
Rio Olympic Velodrome, built immediately west of the Rio Olympic Arena, was conceived, with the Barra Velodrome being demolished in 2013. Other new venues constructed for the Olympics include the
Carioca Arenas, the
Olympic Tennis Center, and the temporary
Olympic Aquatics Stadium, built on the site of the former Barra Velodrome, and
Future Arena venues. Domestic broadcaster
Rede Globo constructed a studio for its coverage of the Games in Barra Olympic Park. ==Venues==
