of the Byzantine time, of the Venetian period, as well as later ones are still
preserved today, in different parts of the city, each one having its own history,
denoting the deep religious belief of the people of Heraklion during their
long history. Some of the churches, like the church of St. Marc is used today
as an exhibition place, while in the church of St. Aikaterini of Sinai, art
works of the Cretan school of iconography are exhibited along with ecclesiastical
vessels, books, sacerdotal vestments and frescoes.
