Collombey-Muraz is a municipality in the district of Monthey in the canton of Valais in Switzerland.
Geography
After the town of Saint-Maurice, the Rhône river flows north towards Lake Geneva. The plain widens on both sides of it, with an area called the Chablais valaisan on its left bank. The district of Monthey is part of it with its nine municipalities, one of which is Collombey-Muraz.
Collombey-Muraz includes the villages of Collombey, Muraz, Collombey-le-Grand, Illarsaz, and Les Neyres. Due to its high proportion of flat ground, it is one of the largest municipalities in the Valais, extending over 29.81 km2.
A survey in 2013-2018 established that housing and infrastructure represented 14.1% of its territory, agricultural areas 36.5%, wooded areas 40.0%, and unproductive areas 9.3%.
Seven alpine pastures, Chalet-Neuf, Conches, Chemeneau, Grand-Crau, Dreveneuse d’en Bas, Chermeux and Onnaz, extend over the heights bordering France. They are owned by the bourgeoisie, who rent them to farmers for the summer season.
The highest point of the municipality, La Pointe de Bellevue at 2,042 metres, offers a view stretching from Lake Geneva to the Dents du Midi. Since 2013, it has given its name to a popular foot race.
The villages
Collombey Collombey is the largest of the municipality's five villages, with nearly 4,600 inhabitants at the end of 2016. It has experienced unprecedented growth since the 1990s with the construction of shopping centers and many residential buildings.
Muraz
On a hillside, Muraz has long suffered from the whims of the two streams bordering it, which have destroyed crops and flooded homes. The village extends on either side of the cantonal road, between a mountain flank and the plain. Like other localities, Muraz has grown considerably and presently has some 2,700 inhabitants.
Collombey-le-Grand
If the "grand" in Collombey-le-Grand ever indicated that the village was bigger or grander than neighbouring Collombey, then that was only true before the 12th century (according to Maurice Parvex, Collombey-Muraz). Today the village still deserves this qualifier if it includes the vast industrial area bordering it. With some 500 inhabitants, the village was originally huddled around the Chapel of Our Lady of the Seven Joys (chapelle Notre Dame des Sept-Joies) before experiencing considerable growth and extending into the plain.
Illarsaz
Illarsaz is a quintessential valley floor village, on the road connecting Vionnaz to Aigle. It was once surrounded by marshes, which have now given way to agriculture. The locality consists mainly of individual villas for a population of about 700 inhabitants.
Les Neyres
On a hillside, nestled between Monthey and Troistorrents, Les Neyres is the fifth and smallest village of the municipality. You have to take the Val d’Illiez road (route du Val d'Illiez) to discover Les Neyres, a scattered habitat of some 400 inhabitants. Like the other villages, Les Neyres has experienced strong growth in recent years, even prompting the municipality to reopen an infant school.
Transport The village of Collombey is served by two railway lines: the CFF Tonkin line (Saint-Maurice – Saint-Gingolph) and the AOMC regional train (Aigle – Ollon – Monthey - Champéry). In addition, a city bus travels hourly to Monthey. The five villages of the municipality are also connected to the surrounding localities by a bus service run by the Public Transport of Chablais (TPC).
Toponymy Collombey derives from the Latin noun cŏlumbārium, which refers either to a dovecote, or to a tomb or to a burial vault. It is not possible to know which applies, even though the municipality’s coat of arms includes doves.
Muraz derives from the Latin noun murum (plural: mura). It refers to a place consisting of remains of walls and constructions. The final z is silent, indicating that the accent is on the u and that the a is atonic.
In Valaisan patois, Collombey is pronounced Collambâ.
History The geographical and political configuration as an autonomous municipality dates back to the division of the castellany of Monthey in 1787.
Geological evolution has left erratic blocks such as the Pierre à Dzo (300 m³), the Pierre à Muguet (1,000 m³), and the Bloc Studer (500 m³). The archaeological site of Châble-Croix, dating back to between 6880 and 6330 BC, could be the oldest in the Valais. From 1900 the exploitation of granite from the ancient glacial moraine uncovered Neolithic necropolises on the heights of Barmaz, dating back to the Neolithic age, around 3000 to 1800 BC.
The history of Collombey-Muraz was essentially agricultural until the 1960s.
