An illegal excavation by an amateur researcher at Metilstein Castle near Eisenach has sparked a debate about the protection of historic sites. The individual, dubbed a 'dirt detective', uncovered walls without authorization, risking damage to the medieval structure. Although he was not accused of deliberate destruction, experts warn that unsupervised digs can lead to the loss of important archaeological information. The incident raises questions about the balance between public interest in history and the need for professional oversight in heritage preservation.
