The Künig Way is a pilgrimage route to Santiago de Compostela that recreates the itinerary described by the German Servite monk Hermann Künig von Vach in his Guide for Pilgrims , first published in Leipzig in 1495. Künig traveled over 4,000 km on his round trip, starting from Einsiedeln (Switzerland) to Santiago de Compostela and then returning via Aachen, meticulously recording churches, hospitals, inns, and potential dangers for pilgrims. This makes his work not only a route guide but also a social and religious chronicle of pilgrimage at the end of the 15th century. Considered the first pilgrim's guide in history, it was a great success, being reprinted several times in that early era of printing. Today, the Künig Way has been revived as an alternative route to the French Way, especially valued for its heritage, its lower crowds, and its landscapes. It has been marked for hikers and pilgrims with posts and signs that follow the original route. In line with these initiatives, it has been recognized as a Historic Route to guarantee its protection, promote its research, and ensure its full integration within the pilgrimage routes to Santiago through the territory of Castilla y León .
