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.
It is the second-largest park in Paris – the size of the park can be imagined by Evelyn’s description of his visit (entry:12th April, 1644):
“I took coach, to see a general muster of all the gens d’armes about the city, in the Bois de Boulogne, before their Majesties and all the Grandees. They were reputed to be near 20,000, besides the spectators, who much exceeded them in number. Here they performed all their motions; and, being drawn up, horse and foot, into several figures, represented a battle.”
John Evelyn visited the Château de Madrid which was located in the Bois de Boulogne.
