A fire believed to have been deliberately set gutted Adolf Hitler’s former mountaintop retreat in Bavaria, a site with a significant amount of U.S. Army history stretching back to near the end of World War II.

The Friday fire caused no injuries or deaths, and investigators are examining possible motives, including political ones linked to the site’s Nazi history. Officers arrested a 33-year-old German national near the Kehlsteinhaus, the historic attraction on Obersalzberg known as the Eagle’s Nest, after he approached emergency crews on a motorcycle on the steep access road leading to the building.

Prosecutors said the suspect showed signs of mental illness and was placed in a secure psychiatric facility, according to a report in the German newspaper Tagesschau. Arson is suspected, it said.

The mountaintop retreat was built by the National Socialist government between 1937 and 1938 and presented to Hitler on his 50th birthday in 1939.

The high-altitude reception house served as a place for Nazi leadership and official guests to gather and converse.

Before the fire, the attraction primarily served as a restaurant and panoramic viewpoint that looked over the town of Berchtesgaden. The extent of the damage is still unclear.

Bavaria’s interior minister, Joachim Herrmann, indicated that the historic site would be rebuilt. “We will hardly be able to leave a ruin standing there,” he said Saturday, according to local media.

Near the end of World War II, U.S. Army units, including elements of the 3rd Infantry Division and later the 101st Airborne Division, reached the area around Berchtesgaden and Obersalzberg in early May 1945.

American soldiers occupied the site, used it briefly as a command post and recreation area, and took souvenirs from the interiors. 

With the building largely spared by Allied bombs, some GIs scratched their names into the red marble fireplace located in the house’s main reception hall. It was a gift from Italian dictator Benito Mussolini to Hitler.

The building later served as part of U.S. forces’ rest-and-recreation facilities until it was returned to Bavarian control.

Generations after the end of the war, American veterans often returned to the Eagle’s Nest, walking the same terraces they had first seen in 1945.

The site remains a destination for U.S. service members stationed in Germany because of its connection to the American occupation of the area. Police continue to investigate the fire.
