Discover more about Heidenloch

The Heidenloch, perched atop Heidelberg's Heiligenberg (Holy Mountain), presents an enigmatic journey into the region's rich and often mysterious past. This intriguing site, also known as the 'Heathen's Hole,' is a shaft plunging 55 meters into the earth, its origins and purpose debated by historians and whispered about in local folklore. The sense of mystery, combined with the stunning panoramic views, makes the Heidenloch a compelling destination for those seeking to delve deeper into Heidelberg's history beyond the famed castle and Old Town. The Heidenloch itself is a man-made cavity, approximately 3 to 4 meters in diameter. Its construction dates back to medieval times, though some theories suggest even earlier origins. The most plausible explanation points to a search for water, perhaps during prehistoric or Roman times. However, the lack of a water source at the bottom of the shaft fuels further speculation. Over the centuries, the shaft underwent various modifications, including lining the bottom with bricks and reinforcing the opening. Excavations in the 20th century unearthed a variety of artifacts, including hewn stones, column fragments, and metal utensils from nearby monasteries. These findings hint at the Heidenloch's possible use as a storage space or even a dumping ground during the Middle Ages. Adding to the enigma, a carved line drawing, known as the "portrait of a woman," was discovered at a depth of 22 meters. Visiting the Heidenloch offers more than just a glimpse into a historical puzzle. The site's location on the Heiligenberg provides breathtaking views of Heidelberg, the Neckar River, and the iconic Heidelberg Castle. The surrounding area is perfect for hiking and exploring other historical landmarks. The Heiligenberg has been inhabited since as early as 5500-5100 BCE, with Celtic settlements dating back to the 5th century BC. The Romans also recognized the mountain's significance, building shrines and temples on its slopes. Today, the Heiligenberg is home to several notable sites, including the Thingstätte, an open-air theater constructed during the Nazi era; the ruins of St. Michael's Monastery, founded in the 9th century; and the remains of St. Stephen's Monastery. A walk along the Celtic Trail connects these historical points, offering a comprehensive exploration of the mountain's past. The Thingstätte, built in 1934-35, stands as a stark reminder of Germany's more recent history. This amphitheater, designed to hold up to 20,000 people, was intended for propaganda events during the Third Reich. Although its original purpose was never fully realized, the Thingstätte remains a powerful and thought-provoking site. The ruins of St. Michael's Monastery offer a glimpse into the Heiligenberg's medieval past. Founded in the 9th century, the monastery became an important center of religious and cultural life. The remains of the monastery church and other buildings can still be seen today.

Although much of the monastery was destroyed over the centuries, the remaining ruins are still impressive. Beyond the historical sites, the Heiligenberg offers a tranquil escape into nature. The mountain is covered in lush forests, with trails winding through the trees.
