Saint-Bélec slab

The Saint-Bélec slab is a stone artefact from western Brittany thought to be a map of an early Bronze Age principality. It was discovered by Paul du Châtellier in a prehistoric burial ground in Finistère, where it formed part of an early Bronze Age cist structure. Du Châtellier kept the slab at his house, the Château de Kernuz, before it came into the collection of the National Archaeological Museum. It was forgotten until 2014 when it was rediscovered in the cellar of the château. A 2017–2021 study by French and British universities and institutes identified the slab as an early Bronze Age map of part of the Odet valley. The slab is the earliest known map found in Europe and probably the earliest map of any known territory.
