On Christmas Eve if a happy mining year came to an end the miners hung her pit lamps on the bill to the wooden curve the mouth hole of the stud spanned. This crooked crossbeam was the real Light arch (Schwibbogen).
At Christmas time the miners hung her lights in a curve on the wall. With it they indicated the stud mouth hole from which they stepped day by day after made work, the darkness of the mountain escaping, in the light. Today at winter time you can see this tradition of Light arches in all villages and many towns. We remember us and put them gladly in the window.
