Much of Parc Monceau is ringed with 18th- and 19th-century mansions, some evoking Proust's Remembrance of Things Past especially since he frequently wandered here. Louis Carrogis Carmontelle designed it in 1778 as a private hideaway for the duc d'Orléans (who came to be known as Philippe-Egalité), at the time the richest man in France. The Duke was a close friend of the Prince of Wales, later George IV, and a lover of all things English. His intention was to create what was then called an Anglo-Chinese or English garden, on the earlier model of Stowe House in England (1730–1738), with its examples of the architectural folly, or fantastic reconstructions of buildings of different ages and continents. It was similar in style to several other examples of the French landscape gardens built at about the same time, including the Desert de Retz, the gardens of the Château de Bagatelle and the Folie Saint James.
