Alpine tent is a large tent used as a temporary building. They have long been used for circus or other performances, fairs, banquets, large weddings or, more recently corporate entertainment events. Traditionally made of canvas, modern party tents are more likely to use best quality canvas for higher quality. Alpine tents are available up to 20 feet (6m) wide. 30 to 150 feet (9m to 45m) widths are very expensive and require specialized equipment and skill.
