On May 25th of 1936 Manousos Pelekis from Ermoupoli had a vision which led him to the icon of Saint Demetrios. After the command of the Metropolitan of Syros at the time, Filaretos a magnificent stone church of Byzantine style with a dome was built in the exact place where the icon was found, a church greeting the ships that arrived. The Temple stands out for the stone walls on the inside as well as the few icons that adorn them. Ships arriving or leaving the port of Ermoupolis whistle just as they pass from St. Demetrios while the priest of the temple, greets them back by ringing the bells.
