Camino Shell greeting card

During centuries of pilgrimage the scallop shell developed into the symbol of the Camino de Santiago. With the possession of the scallop shell, the medieval pilgrims proved their arrival. The scallop shell also acts as a metaphor. The grooves in the shell, which come together at a single point, represent the various routes pilgrims travelled, eventually arriving at a single destination: Santiago de Compostela.
