Fodor's Expert Review Panagia Protothronos
Chalki
Religious Building/Site/Shrine
With its distinct red-roof, this is one of the most important Byzantine churches. Restoration work has uncovered five layers of frescoes from the 6th through the 13th century, and the church has remained alive and functioning for 14 centuries. According to tradition it was named Protothroni because it was the first to be built on Naxos.
