What makes this heritage site unique is not its royal scale, but rather its collective ownership model known as the "condominio." Developed primarily in the 18th and 19th centuries, this model emerged when municipalities and their citizens pooled resources to build, own, and operate theaters collectively, much like how people jointly manage a building. This public-private partnership allowed small and medium-sized towns to possess elegant artistic spaces, while opening theaters to the middle class instead of exclusively serving the aristocracy. Architecturally, the theaters bear the strong imprint of Neoclassical and Post-Baroque styles, boasting optimal sound systems, views, and antique stage equipment.
UNESCO emphasizes the heritage value lies in the sustainable community cultural system, where people have been directly involved in managing and maintaining activities for centuries. The newly honored theaters are scattered across three regions, including eight in the Marche region, one in Emilia-Romagna, and one in Umbria. Among these, the Angelo Mariani Theater in Sant'Agata Feltria (Emilia-Romagna) stands out – Italy's oldest wooden theater.
Italian Culture Minister Alessandro Giuli affirmed that UNESCO's designation honored these "architectural gems" as "centers of community social life" in the country. Currently, all 10 theaters remain vibrant with numerous opera and theatrical performances, continuing a unique tradition of shared culture across generations.
