Scholssberg Caves, Homburg


EntranceDriving into Homburg, it’s hard to miss Castle Rock Mountain. It overlooks the town in Germany’s Saarland region and provides a stunning view of the area. Standing on the top of the mountain, you have no idea that right under your feet is Europe’s largest sandstone cave.

More than 250 million of years ago, wind deposited layers of desert sand that over time formed a mountain. Ocean waves shaped how the sand settled and hardened into the mountain that dominated the landscape. In the seventeenth century, the mountain offered a defendable position and a French fortress was built upon its peak. It was eventually discovered that beneath the fortress, the mountain hid layers of sand tinted yellow and red by quartz and mineral deposits. The yellow sand was prized for the high-quality glass it could produce. The discovery lead to years of mining that resulted in Homburg’s Schlossberg Caves, or the Castle Rock Caves, which form the largest sandstone cave in Europe with twelve separate floors. Though the fortress was eventually destroyed in 1714 when the French turned the territory over to the Germans, the caves remained intact and hidden within the mountain walls.

Fortress ruinsThe caves were largely forgotten during the eighteenth and nineteenth centuries until they were rediscovered in the 1930s by children playing on the mountainside. The caves soon become a popular destination for people who wanted to explore their hidden rooms, enjoy the cool 50° F temperature during hot summer months, and use their winding corridors for parties and concerts. During World War II, the caves took on a new role. They housed up to 5,000 people at a time who were searching for shelter during bombings. Families set up house within the caves with each family carving out a cubby.

Family nook with shelfThe soft sandstone walls allowed them to construct shelves directly in the mountain walls to hold their belongings. After World War II revealed the caves’ protective qualities, a 1950s era bunker was built in one of its caverns.

BunkerToday, visitors can tour the Schlossberg Caves. Tours occur on the hour, and English speaking guides can be requested. The guide leads visitors through one of the cave floors while explaining how the mountain formed and the historical markers that can be observed in the multi-colored layers of sand, such as the red lines that indicate periods of flooding. With the guide’s help, you can even see ripples in the ceiling that resulted from water flowing over the mountain’s exterior millions of years ago and discover roots from a linden tree growing on the mountain’s surface.

SAM_0781Path from top of the mountainThe caves can be reached from several routes once you arrive in Homburg. Visitors can park at the top of Castle Mountain next to the fortress’s ruins and follow the path behind the Schlossberg Hotel to the cave entrance.
