About this picture

Yens is a municipality in the Morges district in the canton of Vaud in Switzerland .


Yens lies at 563  m above sea level. M. , 6 km west of the district capital Morges (linear distance). The village extends on a promontory above the Boiron valley, in the Vaud Central Plateau , in a panoramic position around 200 m above lake level of Lake Geneva .

The 9.5 km² municipal area covers a section of the Vaud Central Plateau in the Lake Geneva region. The south-eastern part of the area is taken up by the open slopes at Yens. To the northwest, the municipality extends over the Boulépenat ( 656  m above sea level ) into a gently undulating hilly landscape in the western edge of the Central Plateau . Here are the headwaters of the Curbit (side stream of the Morges ), the Les Bougeries forest (up to 695  m above sea level ), the headwaters of the Boiron de Morges and the forests of Les Tailles (up to 703  m above sea level ) and Le Sépey (At 715  m above sea level, the highest point in Yens). The south-western border is largely formed by the Boiron stream. In 1997, 7% of the municipal area was accounted for by settlements, 38% for forests and trees and 55% for agriculture.

Yens has several single-family housing estates and some individual farms. The neighboring communities of Yens are Bussy-Chardonney in the east, Denens in the south-east, Villars-sous-Yen in the south-south-east, Lavigny in the south, Saint-Livres in the west, Bière in the north-west, Ballen in the north-north- west and Apple in the north .


With 1,430 inhabitants (as of December 31, 2018), Yens is one of the smaller municipalities in the canton of Vaud. 88.4% of the residents are French-speaking, 4.2% German-speaking and 2.7% Portuguese-speaking (as of 2000). The population of yens was 676 in 1900. After the population had decreased to 516 by 1960, a rapid population increase was observed again with a doubling of the population within 40 years.


Yens was a predominantly agricultural village until the middle of the 20th century . Even today, agriculture and viticulture have an important role in the income structure of the population. There is a larger wine-growing area on the slope below the village. Several mills (including Moulin Martinet and Moulin au Loup) have been using the water power of the Boiron since the end of the Middle Ages . Further jobs are available in local small businesses and in the service sector. In the last few decades the village has developed into a residential community thanks to its attractive location. Many workers are therefore commuters who work mainly in Morges and Lausanne.


Although the community is located away from major thoroughfares, it is still well developed in terms of traffic. It is located above the main road from Aubonne to Cossonay . The motorway connections Aubonne and Morges-Ouest on the A1 (Geneva – Lausanne) opened in 1964 are each around 6 km from the village. On July 1, 1895, the narrow-gauge railway Bière – Apples – Morges with a station in Yens was put into operation.


Remains of a Neolithic settlement and traces from Roman times have been found in the municipality . The first written mention of the place took place in 1030 under the name Idens . Later names were Hiens (1059), Hyens (1223), Jens (1228), for the first time Yens (1232) and Hyenz (1234). The place name goes back to the Burgundian personal name Hiwa and means for the people of Hiwa .

Yens came under the rule of the Lords of Aubonne in the 13th century. The village has shared the fortunes of Aubonne since the conquest of Vaud by Bern in 1536. With the creation of the Aubonne Bailiwick in 1701, Yens was assigned to it. After the collapse of the Ancien Régime , the village belonged to the canton of Léman from 1798 to 1803 during the Helvetic Republic, which then became part of the canton of Vaud when the mediation constitution came into force . In 1798 it was first assigned to the Aubonne district, then in 1803 to the Morges district.


The parish church of Yens was rebuilt in 1862. It has a bell tower of the previous medieval building , which was converted to Baroque style in 1716 . The former castle of the de la Harpe family dates from the 17th and 18th centuries. A classical manor house from the 18th century has also been preserved. In the town center there are some typical farm and wine-growing houses from the 17th to 19th centuries.
