Camino de Santiago pendant that has a shell on the front, and "Camino de Santiago" engraved on the back. Comes with a black cord. Pendent is slightly larger than a 50 euro cent coin, about 25mm.
I believe it is a parking lot in Logroño. As you are following the route through town you need to turn around to see it. I noticed it as I was returning to my albergue after exploring the town.
