The Kristbergsattel is an historical crossing point from the Montafon to the Klostertal.  During the times of mining and pack horse transportation it was used intensively.  There are many tales concerning the crossing point like when the Pope had to stop in Dalaas on his way from Rome to Constance in the year 1400.  The plague had broken out in a neighbouring village and he couldn’t go on.  The people of the Montafon came to the rescue by building him a litter which enabled the head of the church to continue on his journey to Constance.  To show his appreciation the Montafon was granted the privilege of being allowed to use St. Peter’s key in their coat of arms.
