The Château de Polangis, on the site of a manor attested in 1207 was sold in 1623 by the monks of Vincennes to Charles Valdir (or Valliech), secretary to the duc d'Épernon, who rebuilt it; the park was embellished with a rockwork grotto in 1748. In 1790 Polangis belonged to the brother of Honoré de Mirabeau, André Riquetti, vicomte de Mirabeau (1754–1795), called "Mirabeau-Tonneau" a royalist deputy to the Constitutional Assembly, who died in exile at Baden. In 1801 the château was purchased by general Nicolas Oudinot (1767-1847), who organized the 5 floréal an X (2 April 1802) a dinner of officers hostile to Bonaparte: the generals Delmas and Marmont, and colonel Fournier. Chapsal bequeathed it to his adopted son, Auguste Courtin, whose heirs divided the property into house-lots and demolished the château. (French Wikipedia: "Polangis".
