From the pilgrimage church in Santa Maria, via several stations of the Cross, a meditation road (built in 1996) leads you to the oldest religious sanctum of the Alta Pusteria Valley: St. Peter am Kofl. It is said that the chapel was used as a refuge for some priests during the turmoil of the mass migrations from Aguntum (near Lienz in Eastern Tyrol). St. Peter am Kofl was first mentined in 1329 and later renovated in 1987.
