Rueil-Malmaison (or ) is a commune in the western suburbs of Paris, France. It is located 12.6 km. (7.8 miles) from the center of Paris.
In 1928 the name of the commune officially became Rueil-Malmaison in reference to its most famous tourist attraction, the Château de Malmaison, home of Napoléon's first wife Joséphine de Beauharnais.
The name Malmaison comes from Medieval Latin mala mansio, meaning "ill-fated domain", "estate of ill luck". In the Early Middle Ages Malmaison was the site of a royal residence which was destroyed by the Vikings in 846, hence the name.
The Rueil barracks of the Swiss Guard was constructed in 1756 under Louis XV by the architect Axel Guillaumot, and has been a listed Historic Monument since 1973. The Guard was formed by Louis XIII in 1616 and massacred at the Tuileries on 10 August 1792.
During the Franco-Prussian War of 1870, Rueil was located on the front line.
At the end of the 19th century famous painters like Pierre-Auguste Renoir, Edouard Manet and Claude Monet came to paint the Seine which crosses the town.
There are about 850 service sector companies located in Rueil, 70 of which employ more than 100 people. A business district called Rueil-sur-Seine (previously known as "Rueil 2000") was created near the RER A Rueil-Malmaison station to accommodate these companies. The business district is equipped with a fiber-optic network.
Several major French companies have their world headquarters in Rueil-Malmaison, such as Schneider Electric and VINCI. Several large international companies have also located their French headquarters in Rueil-Malmaison, such as ExxonMobil,AstraZeneca and Unilever.
