This large cavity extends deep into the limestone rock (beautiful layering). Former outlet of the Lomme River, today about ten meters above the riverbed. A stunning resurgence that brings an underground river back to the surface.

The Grotte de Lorette-Rochefort is an underground dripstone 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 offers a sleeping place for bats, and there are also some small insects and spiders in the cave. The river Lhomme, 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 rooms, of which the largest and highest (35 meters) is called the Sabbath room. This room, which is 65 metres underground, owes its name to the supposed "witches' sabbath" that, according to the gossip of the first visitors, was held there, because they found a large chief witch there, sitting high up from her chair looking down at a group of other witches forming a coven. In order to rid the cave of its sinister reputation, the cave was recently renamed "Lorette", after the chapel of the Madonna of Loretto near the cave. The cave can be visited with a guide. In addition to the sabbath room, in which a small hot air balloon has been launched during the visit for over 100 years to emphasise the height of the cave, since 2003 the route also leads through the smaller underground room "the Cataclysm".

Recommended with children! At the back of the cave you will find a passage, which takes you through a long, narrow and pitch dark corridor (bring a flashlight!) to another exit.
