The remaining wall is situated in Wambel near the horse race track. Take urban train S4 to Unna and alight the train at Knappschaftskrankenhaus. Walk Talweg into the direction of Dortmund. Don’t be astonished to find the sign of a scallop at the trees of the path. Talweg is part of the old pilgrim route Camino de Santiago (Way of St. James). I think the common pilgrim will nearly come to a heart attack while stumbling along this colourful path.
