Le Goût Rothschild, (pronounced [lə ɡu ʁɔtˈʃild]; English: the Rothschild taste), describes a detailed, elaborate style of interior decoration and living which had its origin in France, Britain, and Germany during the nineteenth century, when the rich, famous, and powerful Rothschild family was at its height. The Rothschild aesthetic and life-style later influenced other rich and powerful families, including the Vanderbilts, Astors, and Rockefellers, and became hallmarks of the American Gilded Age. Aspects of le goût Rothschild continued into the twentieth century, affecting such designers as Yves Saint Laurent and Robert Denning.
The decorative interior elements of the "Goût Rothschild" include lavish use of extravagant heavy textile fabrics (like damask, brocade, and velvet) and much gilding, elaborate stucco ceilings, and precious (and often antique) wooden panelling and parquet flooring. This heavy abundance is combined with eighteenth-century, mostly French, furniture. For the Rothschilds, furniture and works of art often were of royal provenance. The family bought only the best which was on the market at that time, with preference for the reigns of Louis XIV, Louis XV, and Louis XVI. And not so long ago after the French Revolution in 1789, there were some excellent pieces to buy, including many from the Château de Versailles. In architecture, the Rothschilds preferred styles of the Renaissance. The fusion of these uses of materials and styles, "the Rothschild style", combines a sense of Victorian horror vacui beside masterworks of art, sculpture, and armour.
