Kollienta are the traditional carols of Kastoria sung the night of the Christmas Eve by groups of children that go from door to door, as well as in the various local cultural hubs, along with flashing lanterns and a kind of torches (masialades).

Every household in Kastoria knows to perform kollienta in a different way, with song lines dedicated to each family member, whereas to those who do not open the door avoiding the tip or the treat, lyrics get a twisted stinging turn.
