[3] La Tène culture's territorial extent corresponded to what is now France, Belgium, Switzerland, Austria, England, Southern Germany, the Czech Republic, Northern Italy and Central Italy,[4][5] Slovenia, Hungary and Liechtenstein, as well as adjacent parts of the Netherlands, Slovakia,[6] Serbia,[7] Croatia,[8] Transylvania (western Romania), and Transcarpathia (western Ukraine).
It is often distinguished from earlier and neighbouring cultures mainly by the La Tène style of Celtic art, characterized by curving "swirly" decoration, especially of metalwork.
Datable Greek pottery and analysis employing scientific techniques such as dendrochronology and thermoluminescence help provide date ranges for an absolute chronology at some La Tène sites.
[16] In 1994 a prototypical ensemble of elite grave sites of the early 5th century BCE was excavated at Glauberg in Hesse, northeast of Frankfurt-am-Main, in a region that had formerly been considered peripheral to the La Tène sphere.
The establishment of a Greek colony, soon very successful, at Massalia (modern Marseilles) on the Mediterranean coast of France led to great trade with the Hallstatt areas up the Rhone and Saone river systems, and early La Tène elite burials like the Vix Grave in Burgundy contain imported luxury goods along with artifacts produced locally.
The style of "Insular La Tène" art is somewhat different and the artefacts are initially found in some parts of the islands but not others.
By this time, the La Tène style was spreading to the British Isles, though apparently without any significant movements in population.
Herodotus (iv.49) correctly placed Keltoi at the source of the Ister/Danube, in the heartland of La Tène material culture: "The Ister flows right across Europe, rising in the country of the Celts".
Frey (2004) notes that in the 5th century, "burial customs in the Celtic world were not uniform; rather, localised groups had their own beliefs, which, in consequence, also gave rise to distinct artistic expressions".
La Tène metalwork in bronze, iron and gold, developing technologically out of Hallstatt culture, is stylistically characterized by inscribed and inlaid intricate spirals and interlace, on fine bronze vessels, helmets and shields, horse trappings, and elite jewelry, especially the neck rings called torcs and elaborate clasps called fibulae.
It is characterized by elegant, stylized curvilinear animal and vegetal forms, allied with the Hallstatt traditions of geometric patterning.
Burial sites included weapons, carts, and both elite and household goods, evoking a strong continuity with an afterlife.
In Vix, France, an elite woman of the 6th century BCE was buried with a very large bronze "wine-mixer" made in Greece.
Artefacts typical of the La Tène culture were also discovered in stray finds as far afield as Scandinavia, Northern Germany, Poland and in the Balkans.
On the northernmost tip of the lake, between the river and a point south of the village of Epagnier (47°00′16″N 7°00′58″E / 47.0045°N 7.016°E / 47.0045; 7.016), Hansli Kopp, looking for antiquities for Colonel Frédéric Schwab, discovered several rows of wooden piles that still reached up about 50 cm (20 in) into the water.
Weapons predominate, there being 166 swords (most without traces of wear), 270 lanceheads, and 22 shield bosses, along with 385 brooches, tools, and parts of chariots.
An exhibition marking the 150th anniversary of the discovery of the La Tène site opened in 2007 at the Musée Schwab in Biel/Bienne, Switzerland, then Zürich in 2008 and Mont Beuvray in Burgundy in 2009.
[39] A genetic study published in the Journal of Archaeological Science in October 2019 examined 43 maternal and 17 paternal lineages for the La Tène necropolis in Urville-Nacqueville, France, and 27 maternal and 19 paternal lineages for La Tène tumulus of Gurgy Les Noisats near modern Paris, France.
[40] A genetic study published in the Proceedings of the National Academy of Sciences of the United States of America in June 2020 examined the remains of 25 individuals ascribed to the La Tène culture.
The evidence suggested that the Gauls of the La Tène culture largely evolved from local Bronze Age populations.
