The fire alarm sounded at the Kehlsteinhaus on the Obersalzberg in Berchtesgaden at about 9:15 p.m. on Friday, according to a police statement. Firefighters responded immediately but could already see flames clearly visible as they approached. The building sits at 1,834 meters above sea level, making access difficult for fire engines. Emergency crews had to wear respiratory protective equipment to enter the building and its immediate vicinity. No injuries have been reported so far.
The Kehlsteinhaus was built as Adolf Hitler's heavily fortified country residence. It is believed that Hitler partially wrote his book 'Mein Kampf' there. The building survived World War II bombing unscathed and remains a symbol of the Nazi regime. Today it houses a popular restaurant.
A suspect has been arrested, and police are investigating the fire as a criminal incident.
