You are looking at the Green Point Stadium in Cape Town, South Africa. Apart from it being one of the venues for the FIFA 2010 World Cup, the interesting fact is that it is a ’sound proof’ stadium. Well, you need to think about the residents staying around. Right? The stadium has been equipped with the world’s largest glass ceiling to resist the booming sound effect comprising of cheers and screams from escaping the premises. “The 4,700-ton glass roof is supported by 72 radial steel cables arranged symmetrically around the arena to steady the structure against high winds“. The structure was conceived by designers from German engineering firm Schlaich Bergermann.
Undoubtedly, the use of glass ceiling to the once open air stadium have been appreciated by the residents but it will be a double bonanza for the teams in action because the roaring sound of the fantastic crowd is supposed to reflect back [and you know what that means]! The glass bordering also would act as a shield against the fluctuating weather conditions of Cape Town allowing fans to enjoy as much as they can without any interruption.
