In 1836, following a number of divine visitations and dreams of Ioannis Maggioros, Christodoulos Manolas, Manolis Sahas and others, a very old icon of Panagia (Virgin Mary) was found hidden in a mountain in the area of Argokili on Naxos.
The icon is embossed with wax and mastic resin, depicting on one side the Annunciation of the Virgin and on the other the Baptism of Jesus. It is thought to have been created by Luke the Enavgelist and it's estimated to have remained hidden there at least since the period of iconoclasm some 1,000 years earlier –when icons were purged.
One year following its discovery, water began to spring from the same spot where the icon was recovered. The spring was considered sacred since it resembled the relevation of a sacred spring by Theotokos (Virgin Mary) in Valoukli, Constantinople, to a soldier named Leo Marcellus, who later became Byzantine Emperor Leo.
The icon was deposited at the metropolitan church of Paros and Naxos until 1841 when it was moved to an unknown place and its traces were lost.
Until 90 years later, when a girl pupil, Ekaterini Legaki (descendant of Ioannis Maggioros who first discovered the icon) had a vision that the icon was in Naxos, in the estate of Mrs. Xenou, and that the latter would suffer great misfortune if she didn't return the icon to its rightful place. Mrs. Xenou gladly returned the icon, which was brought back to Argokoili with honors. At that day, a number of miracles occured to the flock that had come to celebrate the return.
Today it is kept at the monastery of Panagia Argokiliotissa, which spreads over an area of about 2.5 hectares and includes the old church dating to 1851, a larger new church which is a landmark in the area and a chapel dedicated to the holy water trickling out of the rock opposite the spot where the icon was found.
The church celebrates on the feast day of the Life-Giving Spring (Ζωοδόχου Πηγής), on the Bright Friday in the Eastern Orthodox Church and the Eastern Catholic Churches which follow the Byzantine rite.
Irrespective of your relegion, it is worth visiting Panagia Argokiliotissa to experience the energy of the location and the Panoramic view of the Agean Sea and surrounding islands, since the Temple is located on the top of one of the islands highest mountains.
