Габриэль д’Эстре
Henri IV obtained Chenonceau for his mistress Gabrielle d'Estrées by paying the debts of Catherine de' Medici, which had been inherited by Louise and were threatening to ruin her. In return Louise left the château to her niece Françoise de Lorraine, at that time six years old and betrothed to the four-year-old César de Bourbon, duc de Vendôme, the natural son of Gabrielle d'Estrées and Henri IV. The château belonged to the Duc de Vendôme and his descendants for more than a hundred years. The Bourbons had little interest in the château, except for hunting. In 1650, Louis XIV was the last king of the "ancien régime" to visit.
