Don't miss the church of Panagia Ekatontapiliani which means the church of 100 doors , in Parikia very close to the harbour a 4th century monument, rebuilt after the earthquake of 1773. The original church was built by St. Helen , the mother of St. Constantine, according to the legend .The old town of Parikia is considered to be the biggest in the Cyclades island. You will find alleys untouched from the touristic wave that reduces the beauty of these settlements. Lefkes village is in the middle of the island with many nice tavernas, and beautiful alleys.From Lefkes you can take a very nice walk at the old stones of the Byzantine Route down to Prodromos.
