The castle was classified as a historic monument in 1924. It is the cradle of an exemplary rehabilitation which makes it one of the jewels of the Loire-Atlantique. The defensive architecture of the site is unveiled by a subtle play between the light, the darkness and the hues used. The dynamic lighting tells the story of the castle, sometimes a defensive bulwark, sometimes a place of jubilation. The stone is highlighted by the positioning of the light sources which bring out all the asperities.
Each visit is then a new discovery. Indeed, to limit the phenomenon of weariness, different scenarios of highlighting have been implemented. They are remotely accessible and triggerable from a user-friendly web page. The castle of Clisson thus possesses the appropriate habit of light in all circumstances, depending on the events it welcomes or the time of year.
