Our Lady of Tinos is the major Marian shrine in Greece. It is located in the town of Tinos on the island of Tinos. The complex is built around a miraculous icon which according to tradition was found after the Virgin appeared to the nun Pelagia and revealed to her the place where the icon was buried. The icon is widely believed to be the source of numerous miracles. The church is considered a protectress of seafarers and healer of the infirm. The church was designed by the architect from Tinos, Efstratios Emmanuel Kalonaris in the Renaissance style and was inaugurated in 1830. Since then it constitutes the major Christian pilgrimage in Greece, equal to what is Lourdes in France or Fatima in Portugal. The church receives a vast number of donations in silver and gold votives each year; these are auctioned and used for charities. The church is officially dedicated to the Annunciation of the Virgin Mary. The major feast of the church, however, is on 15 August when the Dormition of the Virgin Mary is commemorated by the Greek Orthodox Church, following the strong tradition of the Aegean Islands where the Dormition is grandly celebrated in mid-August as the principal summer feast.
