The Sonian Forest, also known as the Zoniënwoud, is a large forest area centrally located in Belgium, southeast of Brussels. It covers approximately 4,421 hectares and is best known for its old beech trees, some of which are over 200 years old.
The forest has a rich history dating back to the Iron Age and has had various functions over the centuries, such as providing firewood and timber for the construction of houses and ships, and as a backdrop for hunting scenes.
