  Camp de Mourmelon
  The Camp de Mourmelon (formerly known as Camp de Châlons) is a military camp of circa 10,000 hectares located near Mourmelon-le-Grand  north. It was created at the behest of Napoleon III and opened 30 August 1857 during the Second French Empire.
  The initial purpose was simply for practising military manoeuvres, but it quickly turned into a showcase of the French Imperial Army, a theatrical propaganda display, where French citizens could meet the army and watch parades. Each year the camp was transformed into a town of tents and wooden chalets.
  The camp survived the fall of the Second Empire in 1870, but changed into a training camp and a departure point for troops engaging in overseas operations.
  The camp is used for military manoeuvres, and cavalry training, along with the neighbouring, 2,500 hectare, Camp de Moronvillers. Firing of live ordnance (rockets, missiles) is prohibited.
