Red chalk drawing of Bierjun
This bed chamber was built onto the now-demolished Bierjun farmhouse in Überwasser in 1456 and only revealed its secret beneath ultraviolet light: drawings in red chalk of scenes ranging from the passion of Christ to the mounting of the bell in Pufels church tower, and a bear hunt. These red chalk drawings are a rare example of religious piety in a private rural context before 1500. One farm owner was provost of St. Leonhard's chapel in Pufels in the 17th century.
