Ormesson
Ormesson is a small town in Seine-et-Marne, around 37 km from Melun, 20 km from Fontainebleau, and only 4.6 km from Nemours. Located in the Nemours area, it is close to neighboring villages like Faÿ-lès-Nemours, Châtenoy, and Chevrainvilliers.
Ormesson is significant for its archaeological site, *Les Bossats*, which shows evidence of prehistoric human settlements dating back around 50,000 years. Early Neanderthals used this site for hunting and gathering materials like ochre and flint. Later, Homo sapiens arrived, making tools, hunting bison, and constructing simple stone structures. These findings make *Les Bossats* an important site for understanding prehistoric life in the region.
Archaeologists discovered this site in the 1930s, and since 2009, Pierre Bodu and a CNRS team have conducted regular excavations. They found multiple layers of occupation, including both Neanderthal and Homo sapiens activity, from around 100,000 to 19,000 years ago. The area's rich resources likely made it an attractive place for these groups.
In modern times, Ormesson briefly merged with Châtenoy in 1841 before becoming a separate town again in 1863. Today, Ormesson’s archaeological importance is celebrated as part of France's rich prehistoric heritage.
