The Salzburg catacombs were carved into the rock of the Mönchsberg. The Gertraudenkapelle was consecrated to Thomas Becket in 1178. The remains of the fresco show the martyrdom of the saint. Later the chapel was also consecrated to Gertraud von Nivelles. The romanesque-gothic altar of the Gertraudenkapelle was created in 1865.
