From its first medieval mentions to contemporary developments, Nogent-sur-Vernisson carries centuries of forest and rural history.
Nogent-sur-Vernisson is first mentioned in the 11th century. The name "Nogent" comes from the Latin Novientum, meaning a farming estate. The Vernisson, a small tributary of the Loing, gives the commune its geographic identity.
In the Middle Ages, the village developed around its castle mound and church. Its proximity to the royal Orléans Forest made it a strategic location for hunting and forest management by the kings of France.
