The monumental oak tree next to Kasteel van Gaasbeek, estimated to be around 250 to 260 years old, has been nominated for the 'Tree of the Year' title.

This impressive oak, with a circumference of 5.15 meters, stands as a living testament to the domain's rich history and has served as a backdrop for the castle for centuries.
The tree, which has welcomed generations of visitors and artists under its canopy, now takes center stage. It forms a natural counterpoint to the castle's architecture and serves as a landmark for park visitors.
A vote for this oak is a vote for a piece of living history. If the tree is chosen, the prize money will fund further historical and genetic research into its age and origin.
Furthermore, the winning tree will have the opportunity to represent Belgium next year in the international 'European Tree of the Year' competition.
Voting is open until October 5th via the Boom van het Jaar website.
