The Cave of Lorette-Rochefort is a subterranean stalactite cave in Rochefort in the Belgian province of Namur, a stone's throw from the Caves of Han. Depending on the weather outside the cave, the temperature inside is between 2 and 13 degrees. The cave provides a sleeping place for bats, and there are also some small insects and spiders in the cave. The Lhomme River, which once flowed through the caves, now flows through lower parts of the mountain. Fish that accidentally find themselves in the water only survive for a few days.
The cave contains six halls, of which the largest and highest (35 meters) is called the Sabbath Hall. This hall, which is located 65 meters underground, owes its name to the alleged "witches' Sabbath" that was held there, according to the stories of the first visitors, because they found a large chief witch sitting high in her chair looking down from her chair. , where a group of other witches formed a witch circle.
To rid the cave of its sinister reputation, the cave was recently renamed "Lorette", named after the Madonna of Loretto Chapel near the cave.
The cave can be visited with a guide. In addition to the Sabbath Hall, in which a small hot air balloon has been launched during the visit for more than 100 years to emphasize the height of the cave, the route has also led through the smaller subterranean hall "the Cataclysm" since 2003.
