Hohler Fels, Archaeological cave in Happurg, Germany.
Hohler Fels is a karst cave in Happurg that extends approximately 200 meters in length and 70 meters in width. The entrance faces south, reaches about 6 meters (20 feet) in height, and sits at around 546 meters (1,790 feet) above sea level, positioned directly beneath the remains of a Celtic fortress.
Scientific exploration began in 1906 and 1912 when Konrad Hörmann conducted excavations and discovered remains of Ice Age animals and human artifacts. These finds show that different peoples lived here from the Middle Paleolithic period through the Iron Age.
The cave entrance sits directly beneath a former Celtic settlement, showing how people sought out this location over thousands of years. Different layers of findings tell the story of various groups who lived here and left their mark.
The entrance is easily accessible and the cave can be viewed from outside as you approach the base of the cliff. When you stand beneath the former Houbirg settlement, you are looking at one of the region's oldest human dwellings.
A natural arch with two vaults stands in front of the cave entrance, creating a distinctive geological feature that sets this location apart from other caves. This stone arch was shaped by erosion over millions of years, framing the cave entrance in an unusual way.
