 Nevertheless, the sole surviving document mentioning Mansart's name is a payment of 20,000 "livres" from Longueil in 1657, apparently occasioned by the final completion of the château.A pamphlet with the title "La Mansarade" accuses the architect of having realised, after completing the construction of the first floor, that he had committed an error in the plans and razed everything built so far in order to commence anew.Perrault emphasizes that the architect had the habit of remodeling certain parts of his buildings more than once, in a search for perfection.
