Frauenkirche- Teufelstritt (Devils Footstep)

This is a black mark resembling a footprint with a small hooked tail at the heel, which, according to legend, was where the devil stood when he curiously regarded and ridiculed the "windowless" church that Halsbach had built. In fact, it is a large casting in the square base plate, and none of the side windows can be seen from the spot when one looks to the high altar. In another Version of the Legend the devil made a deal with the builder that no windows were to be built in the church. But the devil was tricked by the clever builder who had set the columns so that you couldn't see a single window from a certain spot in the entrance hall where the devil stood. When the devil found out he was tricked the church was already consecrated so he couldn't enter but left a footprint at the entrance where he madly stomped his foot. (Wikipedia)
