Chenonceau Castle, spanning the Cher River in the Loire Valley UNESCO World Heritage site. Built in the sixteenth century, King Henry II offered Chenonceau to his mistress, Diane de Poitiers. When Henry died, his jealous wife, Catherine de' Medici, forced Diane out of Chenonceau, and grew famous for hosting lavish parties here that included the first ever display of fireworks in France. Chenonceau is the most visited château in France after Versailles.
