Trees of Europe - The Oldest Tree in Paris

Tucked away in a quiet corner of Square René Viviani, just across the river from Notre Dame, stands the oldest tree in Paris — a Robinia pseudoacacia, or Black Locust, planted in 1601.

Despite centuries of war, urbanisation, and environmental change, this tree continues to grow. Its twisted trunk is now partially supported by concrete and steel, a quiet acknowledgment of both its fragility and resilience. Planted during the reign of Henry IV, this Robinia is not only a living piece of history, but also a reminder of how long a tree can endure when given space, care, and cultural value.

Originally native to North America, Robinia pseudoacacia was one of the first American tree species introduced to Europe, and it quickly became naturalised. Its nitrogen-fixing ability and tough timber were valued across the continent. But here in Paris, this particular tree holds a different kind of significance — a symbol of continuity in a city that has seen immense transformation.

As arborists and land managers, it’s a powerful reminder of the long-term perspective our work demands. The trees we plant today could be standing in 2400 — if we choose wisely, and care for them well.
