The village was founded circa 1850 when the French postal services installed a forepost alongside the railroad. Previously the region had been populated by diverse immigration which started under the Roman Empire, which had a great commercial route (the Appian Way) and stopover a few miles away in the city of Autun.
Oslon was the first city where the fighters of the Resistance went when they entered the free zone after the German invasion of France during World War II. The Germans stopped just outside Chalon-sur-Saône. Many Frenchmen died trying to swim across to Oslon and the free zone.
Specialties of the area
The architectural style is predominantly square houses in sandy tones with steep roofs like mountain chalets, as winters are very cold and snowy. This year Oslon was elected the flowery city of the year by the French national board of tourism.
