Saint-Maur
The palace of Saint-Maur-des-Fossés, south east of Paris, was another of Catherine's unfinished projects. She bought this building, on which Philibert de l'Orme had worked, from the heirs of Cardinal Jean du Bellay, after the latter's death in 1560. She then commissioned de l'Orme to finish the work he had begun there. Drawings by Jacques Androuet du Cerceau in the British Museum may shed light on Catherine's intentions for Saint-Maur. They show a plan to enlarge each wing by doubling the size of the pavilions next to the main block of the house. The house was to stay as one storey, with a flat roof and rusticated pilasters. That meant the extensions would not unbalance the masses of the building as seen from the side.
De l'Orme died in 1570; in 1575 an unknown architect took over at Saint-Maur. The new man proposed to heighten the pavilions on the garden side and top them with pitched roofs. He also planned two more arches over de l'Orme's terrace, which joined the pavilions on the garden side. In historian R. J. Knecht's view, the scheme would have given this part of the house, a "colossal, even grotesque" pediment. The work was only partly carried out, and the house was never fit for Catherine to live in.
