It is considered to be remarkable not only for it fantastic architecture and historical background, but also for its amazing collection including Renaissance furniture, period tapestries, and famous art and paintings. It also contains a formal gardens, park, and labyrinth. You can visit Catherine de Medici's famous gardens while you are there.
In 1560, the first-ever fireworks display was seen in France at Chenonceau to mark the ascension to the throne of Catherine's son Francis II. Upon Catherine's death, the castle went to her daughter-in-law, Louise de Lorraine-Vaudemont, who spent most of her remaining days there after the death of her husband.
During the Enlightenment, Louise Dupin was the hostess of this magnificent castle and hosted such figures as Voltaire, Montesquieu, de Marivaux, Buffon, and Rousseau. She is the one who saved the castle during the French Revolution by using it as a supply and commerce post as it had the only bridge with which to cross the river during these difficult times.
