About this Tree
The Stelmužė Oak (Stelmužės ąžuolas), located in the village of Stelmužė in northeastern Lithuania, is widely regarded as the oldest and most revered tree in the country. Estimated to be between 1,000 and 1,500 years old, it predates the formation of the Lithuanian state itself. For centuries, the oak has stood as a silent witness to the passage of eras — from pagan Baltic tribes and medieval kingdoms, through Christianisation, foreign rule, uprisings, occupations, and the eventual restoration of Lithuanian independence. Long before written records, oaks such as this were sacred gathering points, and the Stelmužė Oak is believed to have been part of a pre-Christian ritual landscape where people met, spoke, and marked time beneath its branches.
Botanically, the Stelmužė Oak is a Quercus robur, the pedunculate or common oak — a species that forms the backbone of Europe’s temperate forests. What makes this individual extraordinary is not only its age, but its form. Much of the original trunk has hollowed with time, yet the tree continues to live through vast, sprawling limbs that root the oak firmly in both soil and sky. This structure has turned the oak into a living ecosystem: its cavities shelter birds, bats, insects, fungi, lichens, and microorganisms that depend on ancient trees for survival. In modern Europe, where such veteran oaks are increasingly rare, the Stelmužė Oak represents an irreplaceable reservoir of biodiversity.
For Lithuania, the Stelmužė Oak is more than a biological marvel — it is a national symbol of endurance, continuity, and cultural memory. It embodies a distinctly Baltic relationship with nature, where trees are not resources alone, but elders and witnesses. Protected by law and revered in folklore, the oak stands as a reminder that resilience does not require speed or scale, but patience and rootedness. As Lithuania looks toward a future shaped by ecological responsibility and cultural renewal, the Stelmužė Oak continues to fulfil the role it has held for over a millennium: anchoring the present to deep time, and reminding those who stand beneath it that they are part of a much longer story.

The Story
c. 500–1000 CE
The Oak Takes Root
The Stelmužė Oak begins its life in the forests of what is now northeastern Lithuania, centuries before the formation of the Lithuanian state. It grows during a time when oak trees were revered by Baltic tribes as sacred beings, closely associated with strength, continuity, and the natural order.
Pre-13th Century
A Sacred Gathering Place
Before Christianity reached the region, oaks like the Stelmužė Oak stood at the centre of ritual landscapes. People gathered beneath such trees to mark seasonal cycles, resolve disputes, and honour the forces believed to shape land and life. The oak’s longevity made it a witness to countless human lives and oral histories now lost to time.
13th–15th Century
The Birth of Lithuania
As the Grand Duchy of Lithuania rose to become one of Europe’s largest states, the oak remained rooted in place. It lived through the conversion to Christianity, the building of churches, and the reordering of belief systems — outlasting rulers, borders, and political alliances.
18th–19th Century
Endurance Under Foreign Rule
During centuries of shifting control and occupation, the Stelmužė Oak continued to stand as a familiar presence in the local landscape. For surrounding communities, it became a quiet symbol of continuity at a time when language, land, and identity were under pressure.
1960
Declared a Natural Monument
In 1960, the Stelmužė Oak was officially designated a protected natural monument of Lithuania, recognising its exceptional age, cultural importance, and ecological value. By this time, much of the trunk had hollowed, yet the tree remained alive — supported by its vast, spreading limbs — becoming a national symbol of resilience and continuity.
21st Century
An Ecological Elder
Now estimated to be over a thousand years old, the Stelmužė Oak functions as a rare ecological archive. Its cavities and decaying wood support birds, bats, insects, fungi, and lichens that depend on ancient trees — species increasingly scarce in modern European landscapes. The oak stands today as both a cultural elder and a living ecosystem shaped by deep time.
2026
Entering a New Dialogue
In 2026, the Stelmužė Oak is under consideration for inclusion in the Highly Sensitive Tree (HST) ecosystem — a network of culturally significant trees equipped to sense, communicate, and engage with the public. If included, the oak would enter a new phase of its long life: empowered to share its story, ecological signals, and perspective with people across Lithuania and beyond, continuing its role as a living witness — now with a voice.
