This 15th-century chateau was built in the Gothic and Renaissance styles under the direction of Charles VIII, Louis XII and Francois I. The chateau, the site of the Amboise Conspiracy of 1560 -- an ill-fated plot against Francois II -- fell into disrepair during the Revolution and only a portion of the sprawling compound remains. The Tour des Minimes, the original entrance to the castle, is particularly notable. The Chapelle St-Hubert, perched on the ramparts of the castle, is believed to contain the remains of Leonardo da Vinci, who died in Amboise in 1519.
