Geologically, the springs originate from a subterranean karst river system that emerges through limestone layers.
The water discharge volume remains relatively stable despite seasonal weather fluctuations.
Local traditions associate the number twelve with the biblical apostles, though the site predates Christianization in the region.

Slovenskiye Klyuchi, or the Slavic Springs, are a group of twelve natural karst springs located in the Izborsk-Malskaya Valley, flowing directly into Lake Gorodishchenskoye. The springs are considered a natural monument of regional significance, notable for their consistent year-round discharge rate and water temperature. Archaeological findings suggest the area has been settled since the 7th century, linking the springs to the early history of the Izborsk fortress. The site is a focal point of local religious and folk traditions, with many visitors believing in the healing properties of the water. Twelve distinct streams emerge from the limestone cliffs, often referred to as the 'Twelve Apostles.' The surrounding landscape features protected wetland ecosystems and diverse riparian flora. The water flows into a small pond where swans have historically lived, supported by the Izborsk Museum-Reserve. The site is accessible via wooden walkways designed to protect the sensitive karst terrain from erosion.
