A man has been arrested after a fire broke out at Hitler’s former Alpine retreat, the Kehlsteinhaus, on Friday night.

The blaze erupted at the Kehlsteinhaus, a chalet located on the Obersalzberg near Berchtesgaden in southern Germany. Emergency services responded to the incident, which occurred in the evening, and the building sustained significant damage.

German authorities confirmed that a suspect was detained in connection with the fire. Police have not yet released the individual’s identity or a detailed motive, stating that the investigation is ongoing.

The incident has reignited discussions about the memorialization of sites tied to Nazi history in Germany.
