The Bois de Boulogne 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. The land was ceded to the city of Paris by the Emperor Napoleon III to be turned into a public park in 1852.
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, which is about two and a half times the area of Central Park in New York, slightly less than that of Richmond Park in London, and just under half the size of the Phoenix Park in Dublin.
