Gründelsloch, Karst spring in Kindelbrück, Germany.
Gründelsloch is a karst spring in Kindelbrück that appears as a circular water basin roughly 22 meters across and about 9 meters deep. Clear water flows continuously from several openings at the basin's center.
The spring formed on March 3, 1611, when underground cavities collapsed and created this location. Water has flowed from this natural source continuously since that day.
The spring holds meaning for people in the region as a natural wonder they have relied on for centuries. Visitors today come to witness how water emerges from underground geological formations.
The spring is accessible year-round and maintains constant water temperature between 10 and 11 degrees Celsius throughout the seasons. The clear water makes it easy to observe the depth and structure of the basin from the edge.
The water here contains high amounts of minerals acquired during its long underground journey through the Hainleite rock formations. This mineral composition is a visible sign of how rock has shaped this water source over thousands of years.
