Events took place at eighteen existing venues (eight of which required some redevelopment), nine new venues constructed for the Summer Games, and seven temporary venues which were removed following the conclusion of the games.^[2] Each event was held in one of four geographically segregated Olympic clusters: Barra, Copacabana, Deodoro, Engenho de Dentro and Maracanã. The same was done for the 2007 Pan American Games.^[3][4] Several of the venues are located at the Barra Cluster Olympic Park.^[2] The largest venue at the games in terms of seating capacity is the Estádio do Maracanã, officially known as Jornalista Mário Filho Stadium, which can hold 74,738 spectators and served as the official Olympic Stadium, hosting the opening and closing ceremonies as well as football finals.^[2] In addition, five venues outside Rio de Janeiro hosted football events, in the cities of Brasília, Belo Horizonte, Manaus, Salvador and São Paulo.^[2]

For the first time since the 1900 Summer Olympics, the Opening and Closing Ceremonies for the Summer Olympics weren't held in the same place as athletics events, and all gymnastics events took place in the same arena.
