The origin of Moulin Guillaume dates back to the period when watermills played an essential role in local economies. The mill was powered by running water from nearby streams, which is typical for this region with its varied landscape and natural waterways. The energy of the water was used to grind grain into flour, a crucial activity for the local food supply in earlier centuries. Architecturally, Moulin Guillaume belongs to the traditional rural architectural style of the region. The building is usually constructed from natural stone, which was not only available in the surroundings but also contributed to its durability and integration into the landscape. Its location along waterways is a functional feature that was essential for the operation of the mill. Remnants of the original mechanism or water infrastructure can often still be partially visible at such sites. Ecologically, the environment of Moulin Guillaume is interesting due to the combination of water, forest, and calcareous soil. These factors create a varied ecosystem where both moisture-loving and lime-loving plant species occur. Moreover, old watercourses and ponds contribute to the biodiversity of amphibians and insects.

The Fondry des Chiens in Nismes, also known as the Belgian Grand Canyon, is a natural hollow formed by the seepage of rainwater through the limestone bedrock. It is a unique geological phenomenon and one of the few places in Belgium where you can see such natural gorges. The hollow is approximately 100 metres long and 20 metres deep. The area is surrounded by limestone grassland and dotted with rocks, crevices and caves. The site is rich in rare flowers such as wild orchids and ball daisies, and offers a habitat for various butterflies and lizards. The area is recognised as a nature reserve and is protected because of its vulnerable flora and fauna.

The Moulin Guillaume is a historic water mill located on the banks of the Eau Noire. The mill was first mentioned in 1609 and was originally a ban mill, where residents were obliged to have their grain ground by the appointed miller. The mill was sold in 1850 to a certain Guillaume, hence the name. It was used until 1928 and then dismantled. Since 2013, the mill has been working again and generates green energy. The project was carried out by the municipality and the Parc Naturel Viroin Hermeton. The mill can generate around 30,000 kWh per year, which is enough for the energy policy of around 6 families.

Using the power of moving water to drive a mill wheel is an ancient invention of the human spirit of discovery, the origins of which can be traced back to times long past. Thanks to such a construction, human or animal muscle power could be easily replaced by the power of the natural elements through a watercourse - natural or artificially created - in order to grind grain into corn or press oil from fruit, for example. There are essentially two different ways of driving watermills: * Either the flowing water simply hits the blades of the water wheel from below to set it in motion; or * the water is guided above the wheel - usually through a so-called "mill channel" - and falls onto the blades; this type of construction is more efficient due to natural gravity.

The Fondry des Chiens is a sinkhole in the Viroin-Hermeton Natural Park, located in the municipality of Viroinval, sub-municipality of Nismes, in the Calestienne. This natural phenomenon is a true masterpiece of Mother Nature and has no equal in our country. Over millions of years, water has carved a huge hole in the hard limestone. In some places this hole can be up to 20 meters deep. The rocks in the pit have impossibly soft curves and make it a spectacular sight. Protection: The entire area is integrally protected and is classified as a natural monument. Next to the Fondry des Chiens there is a beautiful calcareous grassland, where thousands of blue flower heads of the rare bollard flower stand out in the spring.
