Humboldteiche, Natural monument and remarkable oak tree in Schlosspark Tegel, Germany.

Humboldteiche is a remarkable ancient oak tree located in Schlosspark Tegel, distinguished by its massive proportions and age. The tree displays the typical structure of an old-growth specimen with a broad powerful trunk and far-reaching crown that towers over the surrounding grounds.

The tree received natural monument status in 1939, reflecting early recognition of significant specimens in Berlin. It later became the subject of preservation efforts aimed at ensuring its long-term survival in the park.

Local tradition suggests Alexander Georg von Humboldt planted this tree, though its estimated age of 400-500 years contradicts this theory.

The tree is located within Schlosspark Tegel and is visible from the surrounding paths, allowing for comfortable viewing without special arrangements. The park itself is easily accessible and provides ample space to view this natural monument from various angles.

In 1970 the oak was given a major restoration costing 6,000 marks, after broken branches, a high share of dead limbs and an infestation by the sulphur polypore fungus had damaged it. Its vitality is now rated as good.
