Campo Imperatore has been popular with filmmakers. The location has been used in more than twenty films, among them The American, The Name of the Rose, Krull, Ladyhawke, Il sole anche di notte, and L'Armata ritorna. Campo Imperatore is a mountain grassland or alpine meadow formed by a high basin shaped plateau. It is the largest plateau of the Apennine ridge. Known as Italy's "Little Tibet", it is located in the Gran Sasso e Monti della Laga National Park. Campo Imperatore has a tectonic origin shaped by alluviums and glaciers. The plateau, which is 27 km in length and an average of 8 km in width, lies adjacent to the Apennines' highest peak Corno Grande, and Europe's southernmost glacier, the Calderone. The plateau's altitude ranges from 1,500 to 1,900 meters. It covers an expanse of approximately 80 km². Campo Imperatore is home to one of Italy's oldest alpine ski resorts.
