The path CoEUR - In the heart of European paths (Nel cuore dei cammini d'Europa) is a devotional and hiking itinerary between Italy and Switzerland. The path CoEUR was born in the late 1990s, when information about Saint Charles Borromeos trips in the northern Piedmont was discovered. After these studies were created the Path of Saint Charles (Cammino di San Carlo) between Arona, the town where the Archbishop was born, and Viverone, the town where the Via Francigena passes through the province of Biella. This track has been used as a starting point to draw the path CoEUR, whose aim is to link all the devotional places along the Lake Maggiore up to Locarno. In its ideal prosecution, the path reaches Einsiedeln abbey connecting the Via Francigena with the Camino de Santiago in its Swiss section, named Via Jacobi.
