Wind-carved cliffs and tidal flats frame the archaeological story of Urville-Nacqueville, a coastal locality on the Cherbourg peninsula in Manche (Normandie). Archaeological data indicates occupation during the Late Iron Age (roughly 120–80 BCE), a time when La Tène-influenced material culture and regional craft traditions shaped the coastal communities of northwestern Gaul. Excavations at Urville-Nacqueville have produced a compact assemblage of Iron Age finds and, more recently, three ancient genomes that provide a genetic window into this community.
The Iron Age Culture of Manche represents a local expression within broader Atlantic and continental networks: metalwork styles and trade connections hint at interaction with neighboring continental groups and with Britain across the Channel. Limited evidence suggests communities here exploited both maritime and terrestrial resources, anchoring a mixed economy of fishing, animal husbandry, and craft production.
Genetic and archaeological lines of evidence together suggest continuity with earlier Bronze Age population substrates in western France, overlaid by Iron Age cultural reorganization. However, the current genetic dataset is small (three samples) and yields tentative inferences about population origins and movements. Archaeological context remains essential for grounding genetic signals: material culture, settlement patterns, and coastal mobility all shape how we interpret the human stories emerging from Urville-Nacqueville.
