From time to time we like to feature unique stories about stone and masonry. Our ancestors had to be creative when it came to recording information. The most common way was carving important information into stone and stone walls.

Recently, a slab of stone with engraved intricate lines and motifs dating as far back to the Bronze Age has been revealed to be Europe’s oldest map, researchers say.

As investigated by CNN, researchers utilized high-resolution 3D surveys and photogrammetry to examine the Saint-Belec Slab – an engraved and partly broken piece of stone that was discovered in 1900 but forgotten about for almost a full century. It was revealed to be the oldest cartographic representation of a known territory in Europe.

The Oldest Map of Western Brittany Recorded

The records of this map show that the slab was moved into a private museum, the National Museum of Archaeology, in the castle of Saint-German-en-Laye, in 1900. In 2014, it was rediscovered in one of the museum’s cellars.

After studying this slab, researchers recognized that its surface was deliberately 3D-shaped to represent a valley with lines in the stone thought to depict a river network. The team of researchers noticed similarities between the engravings and landscape of Western Brittany. There are still many unknowns to this story, including why the slab was broken in the first place.

This study was published in the French Journal Bulletin de la Société préhistorique française.

It is exciting and interesting to learn the different functions of stone, and how it has changed throughout centuries.
