The photo isn´t updated (the arena has been finished) and it´s one of the best football arena in Brazil. The retract roof is something interesting (the weather on the south of Brazil is quite different of the rest of the country).
I believe that a tourist wants to see something different when going to new places. This arena is a state-of-the-art soccer stadium in Brazil and seeing a game here is something to be considered. The place is safe and very friendly for women and kids.
