Unicorn Cave: Journey into Prehistory

The Unicorn Cave, or Einhornhöhle in German, is more than just a cave; it's a portal to the past, a place where myth and science intertwine. Located near Scharzfeld in the Harz Mountains, this natural wonder has captivated visitors for centuries. Its name, steeped in folklore, originates from the medieval belief that the cave was a dwelling place of unicorns, and the bones found within were those of the elusive creature. While modern science has debunked this myth, revealing the bones to be the remains of Ice Age animals, the name and the sense of wonder persist. The cave's history stretches back to the Middle Ages, with the first recorded mention in 1541. In the 17th century, the scientist Otto von Guericke wrote about the discovery of ancient animal bones in the Harz Mountains, sparking the interest of Gottfried Wilhelm Leibniz. Leibniz, a renowned mathematician and philosopher, even created a fictional reconstruction of a unicorn skeleton based on the bones found in the cave. This reconstruction, though based on a misconception, became a symbol of the cave and contributed to its enduring appeal. For centuries, the Unicorn Cave was a site of bone collecting. People believed that the bones, ground into powder, possessed medicinal properties and sold them throughout Europe as "Unicornu fossile." It wasn't until the 19th century that scientist Rudolf Virchow conducted excavations and correctly identified the bones as belonging to extinct animals such as mammoths and cave bears. Over 70 different animal species have been identified within the cave, including 60 species of mammals, such as the cave lion and the wolf, painting a vivid picture of the region's Ice Age fauna. But the Unicorn Cave's story doesn't end with the Ice Age. Scientific excavations have revealed that Neanderthals visited the cave as far back as 100,000 years ago. Stone tools and other artifacts discovered within the cave provide evidence of their presence and offer insights into their lives. In 2021, a giant deer bone was discovered, which is considered the oldest piece of European art ever discovered and attributed to Neanderthals. Today, the Unicorn Cave is a popular tourist destination and an important information center for the Harz – Brunswick Land – Eastphalia National Geopark. Visitors can explore the cave on guided tours, venturing through its narrow corridors and large halls. The tour guides share fascinating stories about the cave's history, geology, and the animals that once roamed its depths. The cave maintains a constant temperature of around 7 degrees Celsius (45 degrees Fahrenheit), so dressing warmly is recommended, even in summer. The cave itself stretches for approximately 610 meters (2,000 feet), with about 270 meters (890 feet) open to the public as a show cave since 1905. As you walk through the cave, you'll marvel at the natural formations, the play of light and shadow, and the sheer scale of the underground chambers. The "Blue Grotto," with its natural entrance and stone steps, is a particularly impressive sight. Beyond the cave itself, the surrounding area offers opportunities for hiking and exploring the Harz Mountains. The Karstwanderweg, a scenic hiking trail, passes near the cave and leads to other natural and historical attractions, such as the Burgruine Scharzfels, a castle ruin perched on a steep mountain edge. The Unicorn Cave also has a checkpoint (no. 101) which is part of the Harzer Wandernadel network of hiking trails. The Unicorn Cave is easily accessible by car, with a free forest parking area located nearby. It can also be reached by public transportation, with a 20-minute signposted hiking trail from Scharzfeld station. The railway station is Barbis – Bad Lauterberg. A visit to the Unicorn Cave is an immersive experience that combines natural history, folklore, and adventure. It's a chance to step back in time, explore the depths of the earth, and discover the secrets of the Harz Mountains.
