Thorigny-sur-Oreuse

--- CONTENT ---
Thorigny-sur-Oreuse is a commune in the Yonne department in north-central France.

The commune is the result of the association of three former communes:

Thorigny, the main town that gave its name to the whole,
Fleurigny, and its hamlet Vallières,
Saint-Martin-sur-Oreuse, and its hamlets Barrault, La Borde and Launay.

Geography

Location

Geology and relief
The area of the municipality is from 83 to .

Thorigny lost his hamlet of La Postolle in 1789 but continues to share with him the old uses granted by the lords of Thorigny.

Hydrography
The commune is at the source of the river Oreuse () a tributary of the Yonne thus of the Seine.

The source of the Oreuse is made up of two elements: "the fountains", under the gate of the church of Thorigny, and the fountain Bouchard, inside the village of Thorigny, which feeds the Rû de Pignevolle which joins the Oreuse in the park of the castle.

In the territory of the three merged communes, there were many ponds: that of the Château de Thorigny (combated to set up the castle park); the castle of Fleurigny; That of Launay's command office.

The water system (and the associated bibs) allowed the operation of an exceptionally high number of water mills in the three municipalities.

Currently, massive water abstractions for the exclusive benefit of Paris distort the hydrological profile of the dewatering valley.

Climate
Although at an altitude comparable to the nearby town of Sens, there is a two-week gap in vegetation.

Channels and transport
At the end of the 19th century, Thorigny took advantage of his presence on the new medieval road connecting Pont-sur-Yonne with Villeneuve-l'Archêque and crossing the Oreuse valley. Fleurigny, on the other hand, ensures a certain importance because of its position as a crossroads with another medieval path from Sens to Nogent-sur-Seine and Trainel. In the 17th century, Thorigny's strong urban development led to Thorigny's disaxement of the Nogent route and a weakening of Fleurigny's role. In the 17th century, the passage from the Orléans National Road to Sedan (No. 51) will consecrate Thorigny's triumph over Fleurigny.

The path of Champagne, perfectly straight, leads from the hamlet of Bruyères to Mauny, Saint-Maurice and Villeneuve-aux-Riches-Hommes.
