Limoges is on the route of the pilgrim route that is known as Santiago de Compostela, a path which has become much more popular in recent years. I hope to do some of this path in 2019, but for a much shorter distance than the expedition that some pilgrims, and walkers, take.
The route of the camino is marked with scallop shells and there are many of these on the streets of Limoges. The French word for scallop is ‘Coquille Saint Jacques’, it is thought because pilgrims used to collect the shells towards the end of their pilgrimage.
