I visited this château on Thursday with my Mother in Law. It's just a few miles from our home in the suburbs of Paris.
It was formerly the residence of Napoléon and Empress Joséphine, and along with the Tuileries it was the headquarters of the French government from 1800 to 1802.
After her divorce from Napoléon, Joséphine received Malmaison in her own right, and remained there until her death in 1814. Napoléon returned and took residence in the house after his defeat at the Battle of Waterloo (1815), before his exile to the island of Saint Helena.
