A "🏟️" is a large structure, often made of concrete or steel, designed to accommodate a large number of people for various events such as sports games, concerts, or exhibitions. It typically has a roof that covers the entire seating area, creating a closed and enclosed space known as a "dome." The dome provides shelter from the elements and allows for controlled climate conditions inside the venue. This architectural feature offers a unique aesthetic appeal and enhances the acoustics, making it an ideal setting for immersive experiences and memorable gatherings.
