Siston was sold before his death to satisfy his creditors, but with a right of repurchase for £2,200.

Starting from the reign of Francis I, the castle and its grounds were entrusted by the king to some of his close associates, either by way of favour (" don pour un temps " - "gift for a time"), or by conditional sale with option of repurchase (" l'engagement ").
