Megonky, Natural monument near Čadca, Slovakia.
Megonky is a natural monument near Čadca featuring sandstone formations that contain numerous rounded stone spheres. These spheres range from about 10 to 260 centimeters in diameter and are spread across the landscape, creating a distinctive geological display where visitors can walk among them.
The site was revealed during quarry explosions in 1988, which uncovered a hidden geological formation previously buried. The formations result from a specific erosion process that worked over a long period to shape these distinctive spheres.
The stone spheres caught the attention of local people who gathered some of them for their gardens, treating the formations as decorative curiosities. This shows how the natural wonder was initially seen through the eyes of those living nearby rather than as a geological site.
The location is easy to find and provides information panels explaining how the formations developed. Wooden benches are placed throughout to help you explore and view the spheres from different angles.
This collection ranks among the largest concentrations of naturally rounded stone spheres on Earth, comparable only to a handful of places outside Europe. The perfectly rounded forms result from an erosion process that is rarely seen worldwide.
