The site of Poilvache may have already been used in the first centuries of our era as a bulwark against invading barbarians. The fortress certainly existed as early as 1228, when it appeared in the archives under the poetic name chastiau d'émeraude (emerald castle), probably thanks to the deep green forests that surrounded it. Over the years, the name was shortened to Méraude, and finally (in the second half of the 13th century) it received the somewhat bewildering name Poilvache (Cowhair). This name may come from a stratagem where enemies hid under cowhides among a herd of live cows, thus managing to infiltrate the fortress. At the height of its history, Poilvache held judicial power over 58 fiefdoms, as well as a mint with the right to coin money. In 1421, Philip the Good, Duke of Burgundy, bought the County of Namur, to which Poilvache belonged at that time. Poilvache was destroyed in 1430 by a group of conspirators from Dinant, Huy, and Liège.

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.

The Montaigle rock formations include: • A limestone massif on which the medieval ruins lie. • Prehistoric caves that bear witness to thousands of years of human occupation. • Historically significant finds that have contributed to our understanding of the Aurignacian culture. • Unique cliffs and boulders with unusual shapes, which are currently protected and where climbing is prohibited.
