The Michelin Guide says that the Hôtel de Ville, or Town Hall, in Noyers has a façade that dates back only to the 18th century. The foundations of the building date to the 12 century, and it was re-built in the 15th. Then, after a fire, it was given a new façade three centuries later. The Hôte de Ville is just across the way from the charcuterie that I posted about earlier.
You can see the plaque on the right in the larger photo above, at the Hôtel de Ville (lower right corner). It shows how high the waters of the Serein River rose in a flood on 25 September 1866.
Noyers has 78 buildings that are classified or registered as monuments historiques, most of them from the 15th century. Most have never been significantly modified over the centuries. Of course there have been floods and fires over that time, but the town has survived fairly unscathed. Nowadays, Noyers lives essentially on tourism.
