Vierberge-Wallfahrt (Vierberge-Lauf, literally: "4-mountain pilgrimage), pilgrimage first mentioned in 1578, leading over the mountains Magdalensberg, Ulrichsberg, Veitsberg and Lorenziberg (north of Klagenfurt) on "3-nails day" (2nd Friday after Easter). The distance of over 40 km has to be covered within 24 hours; pilgrims attend masses and devotions along the way, collect different plants (ivy, periwinkle, juniper) for the "Herrgottswinkel" (a corner of a room with a crucifix and other religious objects frequently found in rural households) and give sweets to children waiting along the way. Unlike earlier interpretations of the pilgrimage as a Celtic pagan cult, modern research places it among the Good Friday processions and Passion plays, developed in the late 15th century in formal analogy with the Jubilee Pilgrimage in Rome.
