Historic Environment Scotland designates the original Hampden Park in Glasgow as a scheduled monument, protecting the site because of its importance in football history. Multiple outlets describe the venue as the world’s first international football stadium. Located on Kingsley Avenue, the ground is associated with early international matches and is credited with influencing the design of later football stadiums. One report notes that the stadium’s early facilities and infrastructure, including elements such as toilets and turnstiles, acted as a model for other venues after its construction. Another outlet says the protected status helps prevent redevelopment plans, including conversion of the site into flats. The designation follows recognition of Hampden Park’s historical role and aims to preserve the character of the original football ground for future generations. The coverage is consistent that the protection is granted through scheduled monument status, reflecting its cultural significance rather than any change in use of the existing football venue.
