The Celts

The western neighbours of the Germanic peoples – and why Caesar's tidy Rhine frontier was in truth an interface.

Family Tree

The Celts were not Germanic – and yet the two are more closely interwoven than Caesar's famous Rhine frontier would have us believe. For centuries the highly developed Celtic cultures shaped their northern neighbours: in craftsmanship, warfare and religion. Many Germanic loanwords come from Celtic.

Sacred groves and druids: the Celtic world was highly organised in religious terms.

The Celts become archaeologically tangible in the Hallstatt (ca. 8th–6th century BC) and La Tène cultures (ca. 450–50 BC) – the latter with its famous, interlaced ornament. Their territory stretched from Iberia across Gaul and the Alps to Britain and Asia Minor.

Gaulish Tribes

Gaul · 1st millennium BC to the Roman conquest

The Helvetii (Swiss plateau; their migration in 58 BC triggered the Gallic War), the Aedui (Burgundy, Rome's „brothers“), the Arverni (Auvergne; home of Vercingetorix), the Senones (who once sacked Rome) and the Carnutes with the sacred centre of Gaul, where the druids gathered every year.

Belgae at the Frontier

Northern Gaul / Rhineland

The Treveri (Trier) and Nervii liked to claim Germanic descent, according to Tacitus – though he himself did not count them as such. Here, in the borderland, Celtic and Germanic identity blurred.

Insular Celts

Britain & Ireland

The British tribes put up bitter resistance to Rome (Boudicca). In Ireland, never conquered by Rome, Celtic culture and language survived longest – together with a rich world of legend.

The Belief of the Celts

Unlike the Germanic peoples, the Celts had a learned priestly caste: the druids, who were judges, teachers and keepers of knowledge all in one. Among the gods were Lugus/Lugh (the „many-skilled one“, present in the name of Lyon/Lugdunum), Taranis (a thunder god with a wheel symbol), Teutates („god of the tribe“) and the horned Cernunnos.

Myth: The „triad of gods“ Teutates–Esus–Taranis is probably only a literary grouping by the poet Lucan, not a genuine cultic trinity. And Caesar's clear separation of Celts and Germanic peoples is today regarded as a rhetorical construct in its own right – the Rhenish matron stones prove how permeable the frontier was.

The Princely Graves – Celtic Wealth You Can Touch

Anyone who thinks spectacular tombs all lie in Egypt has never been to Baden-Württemberg. The princely grave of Hochdorf near Eberdingen is one of archaeology's rare strokes of luck: never robbed, almost completely preserved. When it was excavated in 1978/79 under Jörg Biel, it held a man of about 40, nearly 1.90 m tall – laid out on a bronze couch with little wheels, the like of which has never been found a second time.

This is how a Celtic warrior of the La Tène period might have looked: lime-bleached hair, a heavy neck-ring (torque), an oval shield – and certainly no horned helmet. (AI illustration, based on finds.)
Evidence: Gold fibulae, a golden neck-ring, gold-mounted shoes, a four-wheeled wagon and a huge bronze cauldron (around 500 litres), in which traces of mead could still be detected. Plus nine drinking horns – the largest of iron. Dating: around 530 BC. Today everything stands in the Celtic Museum Hochdorf.

Even more enigmatic is the „Celtic Prince of the Glauberg“ in the Wetterau region of Hesse. In 1996 archaeologists found there a life-size, almost complete sandstone statue of a warrior with armour, sword, shield and neck-ring – without a real counterpart anywhere in the world. Striking is his headgear, the famous „leaf crown“.

Myth: Whether the leaf crown represents a sacred „mistletoe crown“ and the man was a deified ancestor is a charming interpretation – but a hypothesis, not proof. „Prince“ too is modern: we do not know his rank, only his wealth. The statue now stands in the Keltenwelt am Glauberg.

Heuneburg & Manching – Cities Before the Cities

Long before the Romans came, thousands of people already lived here packed closely together. The Heuneburg on the upper Danube surprises with a mudbrick wall in the Mediterranean style – building technique from the Greek world, in the middle of the Swabian Jura of the 6th century BC.

Myth: The label „oldest city north of the Alps“ sounds grand, but it is advertising: it hinges on the question of what one calls a „city“ – experts prefer to speak of „town-like“. And the popular equation with the city of „Pyrene“, mentioned by the Greek Herodotus, cannot be proven; it is conjecture.

A whole size larger was the late-Celtic oppidum of Manching in Bavaria: around 380 hectares, a city wall more than seven kilometres long, plus craft and long-distance trade. In 1999 one of the greatest Celtic gold finds of all came to light here – 483 gold coins.

Evidence & a bitter twist: In November 2022 almost the entire gold hoard was stolen from the Manching museum – all but a single overlooked coin. It has probably long since been melted down. History is fragile, after all.

The Druids – Priests, Judges, the Memory of a People

The Celts had something the Germanic peoples so lacked: a learned class. The druids were priests, judges, teachers and calendar experts all at once. According to Caesar their training lasted up to twenty years – and all knowledge was passed on orally; not a single druidic book has survived. Once a year they gathered in the territory of the Carnutes, which Caesar called „the centre of Gaul“.

The Roman scholar Pliny left us the most famous image: a white-clad priest cutting the sacred mistletoe from an oak with a golden sickle, caught in a white cloth.

Caution: Almost everything we „know“ about druids comes from Roman outsiders with their own agenda – there are no first-hand accounts. Add to this two stubborn errors: Stonehenge was NOT built by druids (it is around 2,000 years older), and the modern Neo-Druids of the 18th/19th century have no documented connection to the ancient ones. And the golden sickle? Pure gold would be far too soft – more likely a symbol or gilded bronze.

Gods, Cauldrons and Sacred Springs

A unified pantheon like that of Olympus never existed – rather hundreds of local gods with countless epithets. A few, however, appear widely: Lugus (lurking in the name of Lyon/Lugdunum), the thunder god Taranis with his wheel, Teutates, the „god of the tribe“, and the antlered Cernunnos, shown on the famous silver cauldron of Gundestrup. The horse goddess Epona was so popular that even Roman cavalrymen adopted her – in the Rhineland too.

The silver cauldron of Gundestrup (a bog find from Jutland) shows a whole world of gods – among them the antlered Cernunnos. Today in the Nationalmuseet Copenhagen.

Especially beautiful is the belief in sacred springs: at the source of the Seine the Gauls worshipped the goddess Sequana, in Bath in England Sulis – both with healing and bathing complexes full of votive offerings.

Myth: The Celts never had an empire-wide pantheon like the Romans – „the one Celtic god“ is always a simplification. And the grisly accounts of human sacrifice in wicker figures („Wicker Man“) come from Caesar, an enemy with good reason to paint the Gauls as barbarians – archaeologically this picture is barely supported.

Celtic Sites in Germany

You don't have to travel to Ireland to find Celtic traces – they lie right on your doorstep:

SiteRegionWhat makes it special
HeuneburgBaden-Württemberg, DanubePrincely seat with a Mediterranean mudbrick wall (6th c. BC)
HochdorfBaden-WürttembergUndisturbed princely grave with gold, bronze couch & mead cauldron

DünsbergHesse, near GießenOppidum with several ring ramparts, battles against Rome
SteinsburgThuringiaMost important oppidum of central Germany
MagdalenenbergBaden-WürttembergOne of the largest burial mounds in Europe, central grave 616 BC
Good to know: The „Hunnenring“ (Ring of the Huns) near Otzenhausen has nothing to do with Huns – the name arose much later. The rampart was built by the Celtic Treveri, the same people who gave Trier its name.

And the tidy border between Celts and Germanic peoples along the Rhine? It was drawn above all by Caesar, because it suited him politically. In truth the Rhine was a passage, not a wall – Celtic loanwords survive in German to this day: the word „Reich“ (from Celtic rīg-, „king“) and even „Eisen“ (iron) are among them. Neighbours, in other words, who learned from one another.
