The top of 2250-foot “Thunder Mountain” was the site of a Celtic Settlement known as the “Oppidum Donnersberg” and it was surrounded by an 8.5 kilometer-long (5.3 miles) stone wall.
The area started to be excavated in 2004 and some parts of the protective wall have been rebuilt for public display.
The settlement was abandoned for unknown reasons in the 2nd century A.D.
Tips for your visit
There is a large parking lot on top of the mountain with plenty of space. You can use this as a springboard to do some serious hiking around the Donnersberg.
