The primary cultural difference between Flanders and Wallonia lies in their linguistic heritage. The Flanders region is predominantly Dutch-speaking, while Wallonia is mainly French-speaking. This has led to distinct cultural identities, with Flanders having closer ties to the Netherlands and Wallonia being more connected to France. Additionally, Flanders is known for its historic cities, architecture, and art, while Wallonia has a more rural, agricultural-focused culture. Both regions have unique customs and traditions, which contribute to the diversity of Belgium as a whole.
