Mirroir d’Eau: Bordeaux’s Modern Marvel

The Mirroir d’Eau in Bordeaux, located opposite the Place de la Bourse, is a relatively new attraction, yet it has already become an iconic symbol of the city. Less than 20 years old, this spectacular installation alternates between extraordinary effects of mirror and mist, captivating visitors of all ages. While it may be a modern addition, the Mirroir d’Eau holds its own against the historic backdrop of the nearly three-century-old building that houses it. Recognised as contemporary world heritage, the Mirroir d’Eau is a place for strolling, dreaming, playing, and cooling off on hot days.

The Magical Transformation

The Mirroir d’Eau’s magic lies in its regular metamorphoses. A mere 2 centimetres of water on a massive granite slab transforms the space into a permanent playground for children, a dreamy spot for lovers, and a refreshing retreat for strollers on warm days, with their feet in the water. Situated between the Garonne River and the 18th-century façade, the Mirroir d’Eau has become the most photographed spot in Bordeaux. 

How It Works?

The Mirroir d’Eau operates through an ingenious system. Water is stored underground in an 800 cubic metre reservoir. Pumps then bring the water to the surface, distributing it through hundreds of channels beneath the slab. The water seeps through the joints of the slab, covering its entire surface. After a pre-programmed interval, an electro-valve system returns the water to the reservoir to regain its optimal temperature. At this point, the fog effect can be activated, with approximately 900 injectors placed at the centre of each slab generating mist, followed by the mirror effect that takes over.

Place de la Bourse

The Place de la Bourse, where the Mirroir d’Eau is located, marks the beginning of the erasure of medieval Bordeaux, which had been enclosed within its walls for centuries. Finally, Bordeaux was liberated! Since 1720, Intendant Boucher, alongside the jurats and parliament, worked to create a royal square and open the fortress city. The choice to enlist Jacques Gabriel, the First Architect of King Louis XV, was decisive. This rectangular square with cut corners, adorned with mascarons and ironwork, embodies the classical city. The Hôtel des Fermes, built by Gabriel the Elder, the Hôtel de la Bourse by Gabriel the Younger, and the isolated central pavilion that finally broke the “wall” (1735-1755) compose this royal square.

Originally, the Place de la Bourse was separated from the river by railings that fell during the Revolution. In the centre, the equestrian statue of the king was replaced by the ephemeral statue of Napoleon, which was itself replaced by the Fountain of the Three Graces in 1869. The success of this fountain knows no bounds, as it remains the most photographed spot in the city.
