Deep in the heart of the Roumare Forest, just a short distance from the historic city of Rouen, lies an extraordinary open-air gallery where nature and art intertwine—The Monumental Forest (La Forêt Monumentale). This breathtaking project transforms the ancient woodland into a realm of imagination, where towering sculptures and immersive installations invite visitors to see the forest in a whole new light.
A Temporary Wonder: June 2024 – September 2026
From June 2024 to September 2026, this major land art exhibition will stretch over four kilometres through the Roumare Forest, offering a unique, ever-evolving dialogue between art and nature. This limited-time showcase makes each visit a special opportunity to witness monumental creativity in harmony with the wilderness.
A Fusion of Nature and Creativity

The Monumental Forest is not just an exhibition—it’s an experience. Conceived as part of the Métropole Rouen Normandie‘s cultural initiatives, this ambitious project brings together artists, architects, and environmentalists to create large-scale artworks that harmonize with the landscape. Each piece is designed to provoke thought, inspire wonder, and deepen the connection between humans and nature.
Since its first edition in 2019, the trail has featured surreal, whimsical, and thought-provoking installations that challenge perceptions of the forest. From giant nests suspended in the treetops to mirrored structures that blend seamlessly into the woodland, every artwork invites exploration and reflection.
A Walk Through the Extraordinary

The four-kilometre trail guides visitors through the Roumare Forest’s ancient oaks, beeches, and pines. Some of the most remarkable past installations include:
- “Les Nids Géants” (The Giant Nests) – Enormous woven nests perched high in the trees, offering a dreamlike perspective of the forest canopy.
- “L’Observatoire” (The Observatory) – A mirrored structure reflecting and distorting the surrounding woods, creating an illusion of infinite nature.
- “La Cabane de l’Oiseau” (The Bird’s Hut) – A wooden cabin balanced precariously on a single tree, symbolizing fragility and resilience.
The 2024-2026 edition promises even more awe-inspiring creations, blending contemporary art with the timeless beauty of the forest.
A Legacy of Art and Environment

The Roumare Forest itself is steeped in history, once a royal hunting ground for Norman dukes and later a vital source of timber for shipbuilding. Today, it serves as a sanctuary for wildlife and a place of recreation. The Monumental Forest project revitalizes this historic woodland, blending contemporary art with ecological awareness.
By integrating art into nature, the exhibition raises questions about humanity’s relationship with the environment—how we protect it, how we coexist with it, and how we can rekindle a sense of wonder for the natural world.
