Tips from the Community
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.
