Fossils of molluscs on Rue Cité-Devant

Rue Cité-Devant
Examine the foot of the building on Rue Cité-Devant just behind the old fountain, and you’ll be able to see fossils of molluscs dating back many millions of years. The fossilised sandstone was extracted north of the Vaud Canton and testifies to the presence far back in time of the vast seas which once covered the whole of the region.
