Parc Monceau is a semi-public park situated in the 8th arrondissement of Paris, France, at the junction of Boulevard de Courcelles, Rue de Prony and Rue Georges Berger. At the main entrance is a rotunda. The park was established by Phillippe d'Orléans, Duke of Chartres, a cousin of the king. He started buying land on which to establish the garden in 1769, and employed Louis Carrogis Carmontelle to design the gardens. He was a close friend of the Prince of Wales, later George IV, and a lover of all things English. As a result, his aim was to create an informal English-style garden in the middle of Paris. By 1778, through successive purchases, the garden had grown to 12 hectares. It became known as the Folie de Chartres.
