Palais Augarten was constructed in the late 17th century by Johann Bernhard Fischer von Erlach on the site of a hunting château and gardens. In 1780 this palace came into the possession of Joseph II, Holy Roman Emperor. Until the beginning of the twentieth century it remained in the possession of the Habsburg family. During this period, and especially in the nineteenth century, many balls were held in the palace, and a salon was opened. Among the guests at that time were Richard Wagner, Franz Liszt, and Hans Makart.
The greatest ball in the Palais Augarten took place on the occasion of the Viennese World's Fair of 1873; among the guests were Emperor Francis Joseph I and Czar Alexander II of Russia. In 1897 the palace was significantly remodelled for the family of Archduke Otto, the nephew of Emperor Francis Joseph.
Despite extensive damage suffered during World War II, the palace has been maintained almost in its original appearance, and many of the original furnishings can still be found there. Today, Palais Augarten is the home and rehearsal space of the Vienna Boys' Choir, who also have their own school there. The palace is located on 130-acre Augarten park, which is the oldest Baroque garden in Vienna.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
