A few sample questions

    Answer: 50,000

    The Colosseum (Flavian Amphitheatre) in Rome could seat approximately 50,000 spectators and had standing room for additional attendees. It featured a retractable awning system (velarium) and an elaborate underground network of tunnels.

  2. 2. The Beijing National Stadium, built for the 2008 Olympics, is commonly known by what nickname?

    Answer: The Bird's Nest

    The Beijing National Stadium is nicknamed 'The Bird's Nest' due to its interwoven steel frame structure that resembles a bird's nest. Designed by Herzog & de Meuron with Ai Weiwei as artistic consultant, it seats 80,000 people.

  3. 3. Which engineering innovation allows SoFi Stadium in Los Angeles to have a translucent roof but no air conditioning?

    Answer: An ETFE (ethylene tetrafluoroethylene) canopy that allows air to flow through

    SoFi Stadium features an ETFE canopy roof that is translucent but not fully enclosed, allowing natural airflow while protecting from rain and sun. The lightweight material lets in natural light and the open sides provide ventilation.

  4. 4. Which stadium was the first to feature a retractable roof?

    Answer: Rogers Centre (SkyDome), Toronto

    The Rogers Centre (originally SkyDome) in Toronto, opened in 1989, was the first stadium with a fully retractable motorized roof. The four-panel roof takes about 20 minutes to open or close.

  5. 5. The Munich Olympic Stadium, built for the 1972 Olympics, is famous for what distinctive architectural feature?

    Answer: A sweeping tensile roof of transparent acrylic panels

    The Munich Olympic Stadium, designed by Frei Otto and Gunter Behnisch, features an iconic tensile canopy of transparent acrylic panels suspended from steel cables. The revolutionary tent-like roof design became a symbol of the 'new Germany.'

Things you'll learn along the way

  • The Houston Astrodome, known as the 'Eighth Wonder of the World,' was the first multi-purpose indoor domed stadium when it opened in 1965. It was also where AstroTurf was invented after natural grass failed to grow under its translucent roof.
  • The new Wembley Stadium features a dramatic 133-meter (436-foot) steel arch that spans the stadium and supports the partially retractable roof. The arch is visible across London and has become an iconic landmark.
  • Al Bayt Stadium, a venue for the 2022 FIFA World Cup in Qatar, features an exterior inspired by the bayt al sha'ar, traditional tents used by nomadic peoples in Qatar. Its tent-like structure pays homage to Qatari heritage.
