Historical studies suggest the oak may be the oldest of its species in the Baltic region.
The interior of the tree's trunk was hollowed out during conservation efforts, revealing historical items like old coins and rusted weaponry.
The tree is located on the site of a former manor that was central to the village's feudal history.
It is the primary natural heritage symbol for the Zarasai region of Lithuania.
Arborists discovered that the oak survived significant lightning strikes and centuries of extreme climate shifts.
The tree has a designated protective fence around its base to prevent soil compaction near the shallow root system.
Stelmužė Oak is the oldest living oak tree in Lithuania and one of the oldest in Europe, with an estimated age ranging from 1,000 to 1,500 years. The tree stands approximately 23 meters tall with a trunk circumference of nearly 9.6 meters at chest height. It is located within the grounds of a historical manor park near the Stelmužė Church. In the late 20th century, conservationists performed significant arboricultural work, including removing rotting wood from the trunk and installing a protective drainage system. The tree has been a protected natural monument of national importance since 1960. The surrounding environment remains rural and quiet, characterized by the adjacent wooden Stelmužė Church, which dates back to the 17th century. The oak is structurally supported by metal rods and cables to manage its heavy, hollowed-out limbs. It remains the centerpiece of the local Stelmužė heritage site in the Zarasai district.
