UNESCO says:
Between the 17th and 20th centuries, the ruling dukes of Liechtenstein transformed their domains in southern Moravia into a striking landscape. It married Baroque architecture (mainly the work of Johann Bernhard Fischer von Erlach) and the classical and neo-Gothic style of the castles of Lednice and Valtice with countryside fashioned according to English romantic principles of landscape architecture. At 200 sq. km, it is one of the largest artificial landscapes in Europe.
