Valdemarsegen

Valdemarsegen is an ancient oak in Corselitze Forest in Denmark, standing 25 meters tall and measuring roughly 9 meters around its trunk. The tree ranks among the largest by volume in Denmark and dominates the forest area in Guldborgsund Municipality with its presence.

The oak originated around 1450 and has therefore lived through about 550 years of time. Its existence bridges different epochs of Danish history together.

The tree carries a name rooted in Danish legend and remains central to local stories that visitors hear when they arrive. Its sheer scale shapes how people experience the forest and draws those who value ancient trees.

The tree sits about 50 meters southeast of Grønsundsvej and is roughly 2 kilometers from Sønder Kirkeby Church. The best route follows the road toward Karleby and then leads into the forest.

The wood contains a volume exceeding 100 cubic meters, making it one of the most massive measured trees in the country. Few visitors know that this volume has determined the shape and stability of the tree across the centuries.
