The La Tène toponym was originally applied to the lakeside area near Epagnier,[4] notable as the eponymous site of the Iron Age archaeological of the La Tène culture.

La Tène has an area, as of 2009[update], of 5.4 square kilometers (2.1 sq mi).

It lies close to Biel/Bienne, at the boundary between French- and German-speaking regions, and at a knot of highways.

[9] Most of the population (as of 2000[update]) speaks French (81.6%) as their first language, German is the second most common (7.2%) and Italian is the third (3.8%).

[9] The Clinique De Préfargier, Maison De Santé and Les Bourguignonnes-les-Perveuils in Marin-Epagnier, the La Tène culture settlement and the Les marais d‘Epagnier prehistoric and medieval sites are listed as Swiss heritage site of national significance.

The Préfargier, Montmirail and Cité Martini areas are part of the Inventory of Swiss Heritage Sites.
