The Bois de Boulogne (French pronunciation: [bwa.d(ə).bu.lɔɲ]) is a large public park located along the western edge of the 16th arrondissement of Paris, near the suburb of Boulogne-Billancourt and Neuilly-sur-Seine. It was created between 1852 and 1858 during the reign of the Emperor Louis Napoleon.
It is the second-largest park in Paris, slightly smaller than the Bois de Vincennes on the eastern side of the city. It covers an area of 845 hectares (2090 acres), which is about two and a half times the area of Central Park in New York and slightly less (88%) than that of Richmond Park in London.
Within the boundaries of the Bois de Boulogne are an English landscape garden with several lakes and a cascade; two smaller botanical and landscape gardens, the Château de Bagatelle and the Pré-Catelan; a zoo and amusement park in the Jardin d'Acclimatation; The Jardin des Serres d'Auteuil, a complex of greenhouses holding a hundred thousand plants; two tracks for horse racing, the Hippodrome de Longchamp and the Auteuil Hippodrome; a tennis stadium where the French Open tennis tournament is held each year; and other attractions.
The Bois de Boulogne is in the 16th arrondissement of Paris, on the western edge of the city.
