What it is

An engraved stone slab that covered a tomb and is interpreted as a scaled depiction of the Odet valley, with relief and river networks. It would be one of the oldest surviving topographic maps in Europe.

The slab was found in 1900 in a tomb and recognised as a possible map in 2021; it was published in 2024. The specific cartographic reading (which territory, what scale) is its researchers' hypothesis and is not unanimous.

What it led to

  • reading the landscape as a territorial record in the Atlantic Early Bronze Age
  • rethinking the antiquity of scaled mapmaking in western Europe
