megastadium
A megastadium is a very large stadium, typically designed to hold a significant number of spectators. While there is no single definitive capacity threshold, it is generally understood to be a stadium with a seating capacity exceeding 50,000. Many megastadiums far surpass this number, accommodating well over 100,000 people. These structures are often built for major sporting events, such as football (soccer) or American football games, as well as large-scale concerts and other public gatherings. The construction of megastadiums is a considerable undertaking, requiring extensive engineering and planning due to their sheer size and the complex infrastructure needed to support such a large audience. They often feature advanced facilities for athletes, media, and VIPs, alongside extensive concessions and amenities for general attendees. The design and location of megastadiums can have a significant impact on urban development and local economies, often serving as focal points for new infrastructure projects and tourism. Due to their scale, they are expensive to build and maintain, and their economic viability is often dependent on attracting a high volume of events and spectators.
