The roof structure accounts for 100% coverage of all spectators, which allows for thermal comfort and adequate ventilation. From any location in the stadium it is possible to see the whole field without any obstructions. The roof collects rain water that is later used to clean the bathrooms and water the green areas.
To reinforce the concept of an arena, which are a type of stadium design that allows the public to be closer to the field, Castelão’s field was lowered and the lowest stands were offset towards the field by 30 m. The distance between the public and the players is of only 10 m.
