Outdoor stadiums are large venues designed for hosting sports events, concerts, and other entertainment activities. They typically feature a grassy field or court in the center, surrounded by seating for thousands of fans. Popular sports played in these stadiums include football, soccer, and baseball. The open-air design allows for a lively atmosphere, especially during sunny days or exciting games. These stadiums often have impressive architecture and can be found in cities around the world. Famous examples include the Colosseum in Rome and Wembley Stadium in London. Many outdoor stadiums also incorporate modern technology, such as large video screens and sound systems, to enhance the spectator experience.
