Bilsteinhöhle, Show cave in Warstein, Germany.
The underground limestone cave system extends nearly 2 kilometers through multiple chambers with formations created by water erosion over millions of years.
Forest worker Franz Kersting discovered the cave in September 1887 during road construction, leading to immediate exploration by geologist Emil Carthaus.
Archaeological excavations within the cave revealed copper daggers and other artifacts indicating the presence of early human settlements in prehistoric times.
The cave maintains a constant temperature of 8 degrees Celsius, requiring visitors to bring warm clothing even during summer months.
An underground river flows through the lower sections of the cave system, continuing to shape the limestone formations through geological processes.
