Between 1853 and 1870, the Emperor Napoleon III and the city's first director of parks and gardens, Jean-Charles Alphand, created the Bois de Boulogne, the Bois de Vincennes, Parc Montsouris and the Parc des Buttes-Chaumont, located at the four points of the compass around the city, as well as many smaller parks, squares and gardens in the Paris' quarters. Since 1977, the city has created 166 new parks, most notably the Parc de la Villette (1987), Parc André Citroën (1992), and Parc de Bercy (1997). One of the newest parks, the Promenade des Berges de la Seine (2013), built on a former highway on the Left Bank of the Seine between the Pont de l'Alma and the Musée d'Orsay, has floating gardens and gives a view of the city's landmarks.
