Lorette-Rochefort Cave
Highlight • Cave
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".

Gatte d'Or Cave
Highlight • Cave
There were a long time when fabric was lacking and banks did not exist. People made little bags out of hairy skin and hid their money where they could. So that sometimes, they would forget them or die with their secret… The unfortunate people without memory make people happy much later!

Grotto of Our Lady of Lourdes
Highlight • Religious Site
The church's memorial day "Our Lady of Lourdes" is on February 11th, which is the anniversary of the Marian apparition (1858), when the Mother of God appeared to 14-year-old Bernadette Soubirous in a rock grotto very close to Lourdes. Bernadette later became a nun and died at the age of just 35. On December 8th (the Feast of the Immaculate Conception of Mary) 1933, she was canonized by Pope Pius XI.
The commemoration of the Madonna of Lourdes is also World Day of the Sick.

Terra Nova is the main visitor center of the Citadel of Namur and is the ideal starting point for discovering the history of this impressive fortress. Through models, audiovisual presentations, and interactive displays, you'll gain a clear overview of the strategic role the citadel played for centuries in defending the city and the Meuse Valley. From Terra Nova, you can also descend into the citadel's underground passages. These tunnels were part of the defense system and served for the movement of soldiers, storage, and protection during sieges. The cool, long passages offer a compelling glimpse into military life and are a fascinating addition to the visible heritage above ground. Today, Terra Nova combines heritage, education, and immersion, making it an essential stop to truly understand the scale, complexity, and history of the Citadel of Namur.

The tramway serves tourist purposes and connects the village center of Han-sur-Lesse with the cave entrance, providing visitors with convenient access to the stalactite cave. The route is currently about 3.1 kilometers long.

The Arville Cave is located near Arville Castle in Faulx-les-Tombes and consists of several smaller cavities collectively known as the "Arville Caves." The most famous cavity is the actual Arville Cave (also known as the Trou du Chantoir), which is located on the northern slope of a paleokarst depression. This depression has a nearly permanent pond at its bottom, the water level of which varies with the seasons. The caves are not open to the public or tourists. They are primarily an interesting karst area for geological and local nature walks.
