Farmasi Arena: A Premier Brazilian Venue

The event was held at the Farmasi Arena, an indoor multipurpose arena located in the Barra da Tijuca region of Rio de Janeiro. The arena boasts a capacity of 15,430 for sports events and up to 18,768 for concerts, making it one of the largest indoor venues in Brazil. Inaugurated for the 2007 Pan American Games, the venue has a rich history, having previously been known as the Arena Olímpica do Rio, HSBC Arena, and Jeunesse Arena.
