The Kesselse Heide is a provincial green space covering 79 hectares, 61 of which are open to the public. The initial acquisition took place in 1978, and it has been expanded since then. The entrance is located in Nijlen, at Vaerestraat 4. The space is freely accessible daily from sunrise to sunset. There are two ponds in the area. These old wells not only provide a pleasant change of scenery but are also a boon for the many plants and animals. Since 1996, the Kesselse Heide has been a protected landscape. It is one of the few remaining remnants of the once vast Kempen heathlands. The heath is a living community created in our region by humans. Historical agricultural practices created a landscape that has been preserved through human intervention: grazing by sheep, burning the heath, and sod cutting. Sod cutting is the removal of the topsoil and vegetation. A dug-out sod of plants and their roots is a sod. If heathland is left untreated, it will evolve into oak and birch forests, and the typical species associated with a heathland habitat will disappear. In the mid-19th century, the Kesselse Heide—like many other parts of the Kempen region—was afforested with Scots pine, a valuable timber for mining. However, during both World Wars, these sod-covered forests were felled, and from then on, the heathland was able to expand again. Current management consists of removing trees and mechanically cutting sods to give the open heathland every chance to thrive. https://youtu.be/NoPf0HSeFz8

The area is characterized by a richly varied and sometimes rare flora. Several historic farm buildings can be found within the area. The Kesselse Heide-Het Goor area, with an area of approximately 2,620 hectares, is located between the villages of Nijlen and Kessel, north of the Lier-Herentals road. The northern border of this area is along Vogelzangstraat, the eastern border along Achterbist, Kannaertsstraat, and Goorstraat. The Grote Steenweg forms the southern border, and the western border is formed by Heidestraat and Vaerestraat. The landscape includes the following topographical areas: "Kannaerdsche Heyde," "Kesselse Heide," "Mol Heide," "Achterbiest," "Het Hoog Bosch," "De Hooge Heide," "Het Armveld," "De Schommers" or "Vissen Eynde," "Het Goor," "Het Goorkasteel," and "Hoge Heyde." Several streams traverse the area, specifically the Goorkantloop, the Elstbeek, the Paddenloop, Blauwe Hoekloop, and the Visbeek. The elevation within the area varies from approximately 5 meters +TAW to approximately 10 meters +TAW.

Mispeldonk Nature Reserve is a beautiful and valuable nature reserve in Bonheiden, located in the province of Antwerp. The area is known for its unique ecosystems, rich biodiversity and the natural beauty of the landscape. Here are some key points about Mispeldonk: Location and Size Mispeldonk is located between Bonheiden and the nearby municipality of Rijmenam, along the banks of the Dijle. The area is part of the larger Dijle landscape, which is known for its wet meadows, meandering waterways and rich flora and fauna. Mispeldonk covers approximately 50 hectares and consists of a mix of marshlands, meadows, forests and ponds. Ecological Importance Mispeldonk is a protected nature reserve because of its special ecological value. The area has a typical structure of a flood plain of the Dijle, which makes it an important habitat for many plant and animal species: • Flora: Various rare and protected plant species grow in the area, such as marsh marigolds, cuckoo flowers and water violets. The wet grasslands and marshes provide unique vegetation that is less common elsewhere in the region. • Fauna: Mispeldonk is an important habitat for birds such as the bluethroat, water rail and reed warbler. Amphibians such as the crested newt and the green frog can also be found there. Furthermore, the area is rich in insects, including butterflies and dragonflies, that thrive in the moist environment. Water management The nature reserve plays an important role in local water management. It is located in a flood-prone area along the Dijle and functions as a natural buffer against flooding. In the event of high water levels, the area can collect water and thus help prevent flooding in nearby villages. The nature reserve contributes to the preservation of water quality by filtering and purifying the water through natural processes. Recreation and Experience Mispeldonk is a popular place for nature lovers and hikers. The area is accessible via various hiking trails that lead through the meadows and forests. There are signposted routes that give walkers the chance to explore the diversity of the landscape and enjoy the peace and quiet of nature. Birdwatchers enjoy visiting the area because of the variety of bird species that can be seen, especially during the breeding season and the migratory bird periods. Management and Protection The nature reserve is managed by Natuurpunt, a Belgian organisation that is committed to nature conservation. Natuurpunt carries out management work to protect biodiversity and maintain the landscape. This includes mowing grasslands, removing invasive plant species and maintaining the walking paths. There is collaboration with local farmers for nature-friendly agriculture, whereby meadows are extensively grazed or mowed, so that they remain suitable for meadow birds and rare plants.

The name "Vrieselhof" goes back to Jan van Vriesele, a nobleman from Kontich who bought approximately 24 hectares of land in Oelegem around 1300 (approximately 32 hectares). In 1975, a year after the sale to the province of Antwerp, the domain was opened to hikers. From 1977 to 1999 the "Provincial Textile and Costume Museum" was located in the Vrieselhof. Due to a lack of resources, only a limited part of the collection could be exhibited. In 2002, the museum moved to Antwerp and was named Fashion Museum Antwerp. In 2003, the Provincial Library Center settled in the castle, together with administrative services. In 2011, a "library of Flemish classics" was opened within the Provincial Library Center. Works by classical Flemish writers are collected and loaned out here. In 2014, the Antwerp provincial council decided to restructure the culture department. The library center would be merged with the Cultural Dissemination and Arts Service into a new Libraries and Arts Service. In 2015, the Provincial Library Center moved to Antwerp, but the collection of Flemish classics remained in the Vrieselhof.

Historical interpretation: The anti-tank ditch is a 33 km long defensive ditch northeast of Antwerp, between the Scheldt and the Albert Canal. The canal was constructed between 1938 and 1940 as part of the Antwerp fortress. In the 1930s, the Belgian army reoriented the fortress into a defense for infantry (support points) and machine gun companies. The military added the anti-tank ditch and bunker lines (KW line) to the existing defense by forts and redoubts. The aim was to stop tanks. That is why the anti-tank ditch had to have a slope, depth and width that a tank of that time could not exceed: a bottom of at least six meters width a width of 18m at the water surface a depth of at least three meters a minimum water level of two meters slopes of 45° Originally, the Antitankgracht was going to be a dry canal, but because it filled up with water, it was forced to be converted into a wet canal. The route had to bridge a height difference of approximately 3 to 18.5 m (DTM). That is why it was divided into about 45 sections with locks. A slide in the lock regulated the water flow and thus maintained the level. The water came partly from seepage water or local streams and partly from the Maas, supplied via the Dessel-Schoten canal. Because control over water levels was so important, each lock was defended by a bunker. The bunkers at the Antitankgracht consist of lock bunkers with flanking daughter bunkers and flanking bunkers. The lock bunkers are elongated free-standing bunkers with a large blank wall, camouflaged by 'eggs' and were usually equipped for two machine guns.
