The Royal Tobacco Factory, an 18th-century industrial building was, at the time it was built the second largest building in Spain, second only to the royal residence El Escorial. It remains one of the largest and most architecturally distinguished industrial buildings ever built in that country, and one of the oldest such buildings to survive.
Since the 1950s it has been the seat of the rectorate of the University of Seville. Prior to that, it was, as its name indicates, a tobacco factory: the most prominent such institution in Europe, and a lineal descendant of Europe's first tobacco factory, which was located nearby. It is one of the most notable and splendid examples of industrial architecture from the era of Spain's Antiguo Régimen.

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.
