The Monastery of Panagia Ekatontapiliani in Paros Greece, Cyclades: The church of Panagia Ekatontapiliani is located few metres from the port of Parikia, the capital of Paros. This is one of the best-preserved Paleochristian monuments in Greece and in fact it is the biggest in size. According to the legend, the original church was constructed by Saint Constantine, first Emperor of Constantinople, after the offering of his mother, Saint Helene.
During her journey to the Holy Land to search for the Holy Cross, a storm brought Saint Helene in Paros, where she promised to the Virgin to build a church if her quest were successful. This church was built by her son Constantine after her death and it was dedicated to the Assumption of the Virgin.
