Rueil-Malmaison, a large green city west of Paris
The fifth most populous town in the Hauts-de-Seine department, Rueil-Malmaison stands out for the size of its territory, one of the largest in the department, which slopes down from wooded heights to the banks of the Seine. This large area explains a density much lower than that of the towns closer to Paris.
Malmaison, the Seine riverbanks and corporate headquarters
The town owes the second part of its name to the Château de Malmaison, the residence of Joséphine de Beauharnais and Bonaparte during the Consulate, now a national museum. Long a village of winegrowers and market gardeners, Rueil-Malmaison became urbanized in the 20th century while keeping vast green spaces, then attracted many corporate headquarters thanks to its proximity to La Défense, as seen in the Rueil-sur-Seine business district. Residential and sought-after, it has seen its population grow steadily since the postwar years.
