The Chinese Pavilion and the unique Court Theatre are particularly valuable parts of the Drottningholm domain. The Theatre auditorium remains unchanged since its completion in 1766.
In 1991, Drottningholm was added to UNESCO's World Heritage List of places that are of outstanding universal value to humanity, representing the best examples of the world´s cultural and natural heritage.
UNESCO inscribed Drottningholm on the World Heritage list for the following reason: The ensemble of Drottningholm - palace, theatre, Chinese pavilion and gardens - is the best example of a royal residence built in the 18th century in Sweden and is representative of all European architecture of that period, heir to the influences exerted by the Chateau of Versailles on the construction of royal residences in western, central and northern Europe.
Properties inscribed on UNESCO´s World Heritage list are of outstanding universal value to humanity, including environments, buildings and landscapes. The UNESCO convention was adopted in 1972 and Sweden signed the convention in 1984. In October 2005 the list included more than 800 objects, of which 14 are in Sweden.
