Klasenheim was a village in Austria-Hungary. A local castle contained artifacts related to the Holy Grail, such as a painting in its chapel. This painting was made by a Franciscan friar, according to the description of one of the Knights of the First Crusade. In July 1906, following the directions of a monk at Cantanez, Henry Jones traveled there with his family. He lodged with his family in Gasthof Trübselig and arranged a trip by a mule drawn cart up to the mountain to visit the castle and study its artifacts.
