I will be in Athens, Santorini, and Mykonos. I would love to know where the best place to buy a cross. Also interested in a greek medallion. thanks for any help.
When we traveled in Greece last September I saw Greek Medallion Pendants on Santorini
in Fira. In Athens several of our tour group members went to a Jewelry Store called Greek Roots. A few of us purchased Greek Medallion bracelets and earrings. This store is located a few minutes south of the Acropolis. Very pleased with the customer service and quality.
There are several stores specifically selling religious items on Apollonos Street in Athens, just on the edge of the Plaka District. This will be your best chance to find what you want.
