The Harchies Marshes, located in Wallonia, have a rich and eventful history. In the 18th century, the Haine Valley was bordered by wet and marshy meadows, but no body of water existed. Between 1925 and 1930, mining caused subsidence, creating depressions invaded by the water table. In the 1950s, the surface area covered by water increased, promoting exceptional biodiversity. Between 1968 and 1971, the site drained, threatening its ecosystem. From 1973-1974, preservation efforts allowed the marsh to revive. In 1986, the site was recognized as a Ramsar area, highlighting its ecological importance. Today, it covers approximately 550 hectares and is classified as a Special Protection Area. It is home to a wide variety of habitats and more than 250 bird species. It remains a popular birdwatching site for birdwatchers and nature lovers.

When in Bernissart, a visit to the Iguanodon Museum is a must! This cool museum clearly explains how the dinosaurs were discovered and how they found their way to the museum. Follow the dinosaur footprints and let them take you along in their story! 🦕
