One of the most significant monuments of Christianity is the Church of Panagia Ekatontapiliani (Our Lady of a Hundred Gates), being one of the most important Byzantine monument around Greece. Located only 200 meters from the port of Parikia, this legendary church actually consisting of three linked churches was named after the large number of doors set in the building. The church’s history begins in the 4th century AD during Saint Helen’s quest for the Holly Cross and Paros was one of her stopovers, where she promised that once finding it, she would build a grand church in Virgin Mary’s name, a promise kept by her son Emperor Constantine the Great. The church includes unique domes and vaults, old Byzantine icons and religious artifacts, along with an Ecclesiastical museum and shop. Right behind the Ekatontapiliani church is the Archaeological Museum of Paros, where the history of the island unfolds in front of its visitor’s eyes.

In the heart of the island is the small village of Marathi to host the Ancient Marble Quarry dating back to the 3rd millennia BC. After crossing a marble path between old buildings visitors can se the entrance of the quarry with its corridors, stoas and some inscriptions, where the legend of Parian marble revives since it was used in the manufacture of the greatest greek masterpieces such as Aphrodite of Milo, the Maidens of the Acopolis, the Niki of Delos and the Hermes of Praxiteles, as well as the Sifnian Treasure and the Temple of Apollo in Delphi, the Temple of Zeus in Olympia and Temple of Apollo in Delos.
