Witseboom, Protected lime tree in Vlezenbeek, Belgium.

Witseboom is a summer lime tree standing beside a dirt and gravel path on the Puttenberg in Vlezenbeek, part of Sint-Pieters-Leeuw. Its thick dark trunk rises from a grassy base with a low wooden fence rail and a small white marker post, and its dense green canopy is taller than it is wide. A protected zone of 28 metres around the tree was designated in 2010.

The tree received protected monument status in 2010 when Belgian minister Geert Bourgeois designated it and its surrounding area for preservation. This recognition reflected its importance to the region.

The tree became known through the Flemish television series Witse, which aired from 2004 to 2012 and gave it a special place in local memory. Visitors today often recognize it because of this connection to the show that many in the region watched.

The protected zone around the tree means that any changes or work in this area require special permits and authorization. Visitors can freely approach the monument while respecting its conservation status.

The tree is a summer lime (zomerlinde), not a generic lime, and it stands on the Puttenberg in Vlezenbeek, part of Sint-Pieters-Leeuw in the Pajottenland, although the series Witse is set in Halle. The protected zone covers 28 metres around the trunk.
