Embedded in the streets of Segovia are the occasional route markers.  These are aids-in-navigation for walkers who are intent on following a particular path.  This one, a scallop shell, is the traditional symbol for the camino to Santiago de Compostela.  It guides pilgrims who are headed to Santiago in northwest Spain on their pilgrim route to the shrine of St. James.

I don't know what this one signifies.  I'm hoping Cheryl Riley will help me out here.

This plaque and several more that are similar or identical mark the boundaries of the former Jewish Quarter of Segovia.  They were placed by an organization dedicated to documenting the Jewish presence in Spain.

The aqueduct was partially disassembled about 50 years ago and replaced with modern plumbing.  This marker follows the original route of the aqueduct.
