Until the middle of the 20th century, Lonay was predominantly an agricultural village. Even today, agriculture and viticulture on the slopes around Lonay have a certain importance in the income structure of the population.

The first handicraft business in the municipality was a brickworks founded in 1437, which was mechanized in 1880 and was one of the most important in western Switzerland until it was closed in 1913. Since the 1970s, several industrial and commercial zones have been created in the valley below Lonay along the main traffic axes, which offer numerous jobs. These include companies in electronics, mechanical engineering, the plastics and food industries. 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 primarily in Lausanne and Morges.

On July 1, 1855, the Renens – Morges section of the Lausanne – Geneva railway line was inaugurated with the Lonay-Préverenges station. From 1969 to 1971, the large Lausanne marshalling yard of the SBB was built, which with a track length of 60 km takes up around 15 hectares of the municipality of Lonay; the eastern part is in the Denges area.


Finds of Roman and early medieval graves indicate an early settlement of the municipality. The first written mention of the place took place in 1177 under the current name Lonay . In 1213 the name Losnai appeared . The place name goes back to the Latin personal name Lonius .

In Lonay the Lausanne cathedral chapter and the Lac de Joux ( L'Abbaye ) abbey owned rich estates. Lonay was split into numerous fiefs.

After the collapse of the Ancien Régime , Lonay 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 assigned to the Morges district.


The parish church of Saint-Germain was rebuilt in 1740–1741 on the site of a medieval predecessor building, including the early Gothic choir. The rectory has been in a former winery of the Lac de Joux Abbey since the 18th century. In the old town center of Lonay there are some characteristic farm and wine farms from the 17th to 19th centuries.

In Roman there is the Saint-Maurice chapel from the 14th century. The mansion in Roman lingerie dates from the 17th and 18th centuries. The late medieval house La Réale in Roman-Dessus has a large roof in the Bernese style.
