All along the river

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. The land was ceded to the city of Paris by the Emperor Napoleon III to be turned into a public park in 1852.

The Château de Madrid was a Renaissance building in France. It was built in Neuilly, on the edge of the Bois de Boulogne, near Paris in the early 16th century. It fell into disuse in the 17th and 18th centuries and was almost completely demolished in the 1790s.
