Every September, Paris throws open the doors to its rich history. The European Heritage Days return on September 20 and 21, 2025, for their 42nd edition, centered around architectural heritage—a rich and inspiring theme that invites you to explore the city from a new perspective.
A Weekend at the Heart of Parisian Architectural Heritage
From the elegance of Haussmannian buildings to the hidden gems of Art Deco, and even contemporary architecture, Paris reveals its architectural legacy in a whole new way.
This 2025 edition offers the perfect opportunity to visit places that are usually closed to the public—private mansions, government ministries, theaters backstage, craftsmen’s workshops, hidden courtyards, and even panoramic rooftops—all free of charge.
For guests staying at one of the Compagnie Hôtelière de Bagatelle establishments, it’s the perfect chance to experience Paris like a true insider, just steps away from their hotel.
A Cultural and Historical Event Not to Be Missed
Created in 1984 by the Ministry of Culture, the Heritage Days have become a major European event. Each year, they attract millions of curious visitors, history buffs, architecture enthusiasts, and culture lovers.
In Paris, you’ll find guided tours, exhibitions, concerts, and lectures focused on architecture—its styles, materials, and evolution. It’s a true deep dive into the craftsmanship that shaped the City of Light.
Extend the Experience in Our Charming Hotels
Ideally located in some of the most beautiful neighborhoods of the capital, the Compagnie Hôtelière de Bagatelle hotels combine comfort, elegance, and authenticity.
