Ancient Stories Carved in Stone: The Holsteen of Zonhoven

The Holsteen is a remarkable ensemble of Miocene sandstone formations situated within the Belgian municipality of Zonhoven. Comprising 10 substantial rocks, these formations are composed of quartz-rich marine sand, deposited around 15 million years ago during the Miocene epoch. 

The largest among them stands at an impressive 8 meters in height and 5 meters in width, distinguished by their intriguing perforations and grooves. The multitude of circular hollows and perforations on the rocks can be attributed to natural processes rather than human intervention. These formations primarily showcase evidence of fossilized animal burrows and root channels, eroded over time by the forces of water and wind. 

However, some of the grooves are believed to have been contributed by prehistoric individuals who utilized these rocks as tools for polishing. Notably, the town hall of Zonhoven boasts a permanent exhibition housing archaeological artifacts recovered from the Holsteen. 

Undoubtedly, the Holsteen holds immense archaeological significance. It offers invaluable insights into the lifestyles and toolcrafting techniques of our prehistoric ancestors. Furthermore, the rocks have become a popular draw for tourists, nestled within the scenic expanse of the De Teut nature reserve. This reserve is a favored destination for hiking and biking enthusiasts alike.
