Located at 25 avenue des Champs Elysees, the Hôtel de la Païva was the home of the Marquise de la Païva, a famous 19th-century courtesan. Built in the decade from 1856-66 by the architect Pierre Manguin, this mansion is the sole remaining example of the magnificent palaces that once lined the Champs Élysées. It is a remarkable and rare example of the Second Empire‘s architecture and is listed as a UNESCO World Heritage monument. It was decorated by the greatest artists of the time in Renaissance style. The Hôtel de la Païva, with its large yellow onyx staircase, Moorish-style bathroom, sculptures, paintings, and a ceiling by Paul Baudry, is a unique place.
