Cernex is a French commune in the department of Haute-Savoie in the region of Auvergne Rhône-Alpes .


Cernex is located at 576  m , about 19 kilometers north of the city of Annecy (as the crow flies). The village extends in a panoramic location on the southern slope of the Montagne de Sion, a western foothill of the Salève , in a basin of the Nant Trouble, in the Genevois .

The area of ​​the 12.66 km² large municipal area includes a section of the Genevois. The southern border runs along the Usses , a left tributary of the Rhone , which flows here in a deep valley from east to west. From the course of the river, the municipal area extends northward onto the slopes and terraces on both sides of the valley of the Nant Trouble and into the wooded area of ​​the Bois Chardon . In the west, the Ruisseau de Mostan forms the border. To the north, the municipality extends to the broad ridge of the Montagne de Sion, on which the highest point of Cernex is reached at 857  m .

In addition to the actual town center, Cernex also includes various hamlet settlements and farms, including:

  • La Chapelle ( 510  m ) on a plateau between the valleys of the Ruisseau de Mostan and the Nant Trouble
  • Veyssières ( 500  m ) in the valley of Nant Trouble
  • Cortenges ( 640  m ) on the slope above the village
  • La Motte ( 688  m ) on the southern slope of the Montagne de Sion
  • Verlioz ( 690  m ) on the southern slope of the Montagne de Sion
  • Chez Gresat ( 770  m ) on the ridge of the Montagne de Sion

Neighboring communities of Cernex are Vers in the north, Andilly and Copponex in the east, Cercier in the south and Marlioz , Chavannaz and Minzier in the west.


Cernex was first mentioned in a document in 1208. Later the spellings Sernai , Sernay and Sernex appeared . The place name originally comes from the Latin word circinata [terra] (fenced, fenced land). In the 15th and 16th centuries, Cernex was the center of a small dominion that came into the possession of Thomas of Savoy in 1643.


The village church of Saint-Martin was built between 1530 and 1535. The former mansion has also been preserved.

With 1010 inhabitants (as of January 1, 2017), Cernex is one of the small communities in the Haute-Savoie department. In the course of the 19th and 20th centuries, the number of inhabitants decreased continuously due to strong emigration (in 1861 there were still 911 inhabitants in Cernex). Since the mid-1970s, however, there has been a significant increase in population thanks to the attractive residential area.

Economy and Infrastructure

Cernex is still a predominantly agricultural village today . There are also some local small businesses. A large number of workers are commuters who work in the larger towns in the area as well as in the Annecy and Geneva-Annemasse area.

The village is located off the main thoroughfares on a departmental road that leads from Andilly to Sallenôves . Further road connections exist with Vers and Chavannaz. The closest connection to the A41 motorway is around 12 km away.
