Nyon

The chateau of Nyon

Nyon is a municipality in the district of Nyon in the canton of Vaud in Switzerland. It is located some 25 kilometers north of Geneva's downtown, and since the 1970s it has become part of the Geneva metropolitan area. It lies on the shores of Lake Geneva, and is the seat of the district of Nyon. The town has (as of 2006) 17,267 inhabitants.




Nyon derives from one of the names used by the Romans for the town, Noviodunum or Noiodunum. Other names for the town, particularly of colonies placed there, are Colonia Iulia Equestris or Colonia Julia Equestris, Colonia Equestris Noiodunum, Equestris, Civitas Equestrium, and Civitas Equestrium Noiodunum.

It was founded by the Romans between 50 and 44 BCE under the name of Colonia Iulia Equestris or Colonia Equestris Noiodunum, the urban center of which was called Noviodunum. It grew to be one of the most important Roman colonies in modern-day Switzerland, with a forum, a basilica and an amphitheater that was discovered only recently, in 1996, when digging for the construction of a new building.

At Roman contact, the country round the town was held by the Helvetii. The town's importance is reflected in its numerous mentions in ancient sources. The Antonine Itineraries place the town on the road from Geneva to Lacus Lausonius (near Lausanne). It is first mentioned by Pliny, and then by Ptolemy, who assigns it to the Sequani. Pliny and Ptolemy simply name it Equestris; and so it is named in the Itineraries. On some inscriptions it is called Civ. Equestrium (short for Civitas Equestrium), and Col. Julia Equ. (short for Colonia Julia Equestris) from which some have concluded that it was founded by Julius Caesar. In the Notitia it is called Civ. Equestrium Noiodunum (short for Civitas Equestrium Noiodunum). The district in which Nyon stands is called Pagus Equestricus in a document of the year 1011; and it is said that the people of the country as of the 18th century still called this district Enquestre.
