Who was the original owner of the Chateau de Chambord?

King François I ordered the Chateau to be built. He was the original owner, and wanted it to be closer to his mistress, and used it for hunting trips.

For more than 80 years after the death of King François, French kings abandoned the château, allowing it to fall into decay. Finally, in 1639 King Louis XIII gave it to his brother, Gaston d'Orléans, who saved the château from ruin by carrying out much restoration work. King Louis XIV had the great keep restored and furnished the royal apartments. The king then added a 1,200-horse stable, enabling him to use the château as a hunting lodge and a place to entertain a few weeks each year. Nonetheless, Louis XIV abandoned the château in 1685. From 1725 to 1733, Stanislas Leszczyński (Stanislas I), the deposed King of Poland and father-in-law of King Louis XV, lived at Chambord. In 1745, as a reward for valour, the king gave the château to Maurice de Saxe, Marshal of France who installed his military regiment there. Maurice de Saxe died in 1750 and once again the colossal château sat empty for many years.
