In front of the castle of the dukes of Brittany
After one year of work, the "Miroir d'eau" was put into service on 5 September 2015.
Most of the time, it will be covered with a thin film of 2 cm of water, reflecting the image of the castle. But, thanks to the 208 points of misting, it can also diffuse fine particles of water creating a refreshing mist. Or spray up to 32 vertical jets up to 1.50 meters. The water jets should activate about ten minutes per hour, as well as the evening when they will be illuminated in different colors. The water mirror, fed by a huge reservoir of water in the basement, will remain permanently active, even in winter, like other fountains in the city (except in case of frost).
