Legend of the Teufelsgraben - Taken from Sagen.at
The devil once stood near wooden churches, leaned on a shovel and pondered what he could do to people. Full of anger and hatred, he looked at the capital because the Munich residents were too Christian for him, so that because of their many devotions he could not find a place among them. Then he got the idea to cut off the water for them in revenge and to lead the Isar to the Chiemsee. He quickly got to work and began digging at night as if he had grown a thousand hands. When he was in full swing, the Messner von Foching joined in, who - so as not to oversleep the prayers - had already got up at midnight. When he heard the noise and saw all the digging and shoveling, digging and throwing, and how the earth was flying right and left, he asked: "What are you doing there?" - The evil one growled: "And if I want to divert the Isar from here, what is that to you?" - "One could think so," replied the measurer, "You would like to come about with it today. You will need several years!" - "If there is a wager for your soul," replied the godfather, "before the morning bell rings, I'll be done with the dig." - "It is true," replied the clerk, "even if I don't see anything out of it". But soon he was horrified by the uncanny stranger, he turned the church clock forward two hours and rang the prayer bell at 3 o'clock. Immediately all the roosters came alive and with their crowing broke the magic of the night. The devil, however, in anger that he had miscalculated in time or was outwitted, threw away pimples and shovels, gave up his work and went to hell.
