Father Schwarz’s website, 4kmh.com says:
The The Via Alpina Sacra is the attempt at the longest pilgrimage route through the alps connecting 8 countries and more than 200 of the largest, most beautiful, oldest, highest, most significant Catholic shrines, churches and monasteries. Its length is about 2550 miles (4100km) with 600.000 vertical feet (180.000m) of positive elevation change (i.e. counting only ups). Its starting point is the patriarchal basilica of Aquileia (Italy). Its end point is one of the oldest monastic settlements in the West on the island of Saint-Honorat (410) off Cannes (France).
Today he posted this photo (see below) of the stunning Patriarchal Basilica of Aquileia on the northern end of the Adriatic Sea, near Grado, where he begins his pilgrimage.
