Château de Bois-Préau stands in Rueil-Malmaison, Hauts-de-Seine, situated within a 17-hectare English-style park. Originating in the Middle Ages under the abbey of Saint-Denis, the estate was developed between 1697 and 1700 by printers Frédéric Léonard and his son, who built the house surrounded by gardens and water features. Josephine Bonaparte acquired it in 1810, establishing part of her library and natural history cabinet before commissioning landscape architect Louis-Martin Berthault to redesign the gardens. In 1926, American patron Edward Tuck donated Bois-Préau to the French state as a museum annex to Château de Malmaison. Today, it houses a national museum dedicated to Napoleon, featuring exhibitions about his captivity and the Napoleonic era, recently enhanced with reconstructed rooms and expanded collections.
