Glocknerwallfahrt

The Glockner pilgrimage, traditionally known as the Pinzgau pilgrimage, is Salzburg's largest pilgrimage and has been taking place on 28 June, the day before the church feast day of the apostles Peter and Paul, for around 300 years. 
According to tradition, the Pinzgau pilgrimage goes back to a vow made towards the end of the Middle Ages, in which the pilgrims asked for protection from the plague and wolves. 

Every year, thousands of pilgrims make the pilgrimage from Seidlwinkltal in Rauris and Fusch in Salzburger Land via the Grossglockner High Alpine Road to Heiligenblut in Carinthia.
