History and context
Heuneburg raised a mudbrick wall on a stone plinth, protected by a clear coating and reinforced with towers. Its form was not usual in central Europe and reveals the circulation of constructive ideas, craftsmen or both.
The wall does not prove that Greek architects directed the work. It demonstrates something more interesting: a local community selected and adapted a foreign solution to its landscape, while the settlement articulated neighbourhoods, production and elite burial mounds.
At the beginning of the 6th century BCE, the air-dried mudbrick wall replaced a wood-and-earth defence. Projecting bastions and clear render created a silhouette without known parallel north of the Alps.
The acropolis of about three hectares was only part of the ensemble: outer bailey and external settlement expanded the population and activities. Attic pottery and other imports situate the innovation within contacts, not an isolated copy.
Evidence and interpretation
Documented fact: the archaeological ensemble of Heuneburg preserves and reconstructs a mudbrick fortification of the early Iron Age. Interpretation and caution: the exact route of technical knowledge and the identity of its builders remain open. Documented expansion: The mudbrick wall with bastions dates to ca. 600 BCE; the site prospered approximately between 650 and 450 BCE and had suburbs outside the citadel. Expanded interpretation and caution: Mediterranean inspiration does not demonstrate Greek architects present; population and extent figures change with new surveys.

Objects connected through time
Follow a topic across the collections. A shared tag is a way to compare objects, not proof that one culture influenced another.
The order uses the midpoint of each approximate date range; ranges can overlap. Spacing does not represent elapsed time. Swipe, scroll or use the arrows. With the sequence focused, use ← / →, Home or End.

The fire did not close all the cemeteries
The destruction by fire of the mudbrick-walled settlement, around 540 BCE, was used to date also the abandonment of the Hohmichele burial group. However, excavations of barrows 17 and 18 carried out between 1999 and 2002 documented burials later, up to at least 450 BCE. The life of the funerary landscape thus underwent important changes alongside the settlement. Defences, houses and cemeteries did not obey a single final date: communities continued using certain places of memory after transforming other spaces.
