The Hôtel de Sully, headquarters of the Centre des monuments nationaux, is one of the most beautiful private mansions in the Marais district in Paris. To improve its presentation to the public, in 2008 and 2009 it underwent an extensive restoration campaign.
The restoration campaign, both external and internal, was conducted on behalf of the CMN under the project ownership of the Service national des travaux, with chief architect of Historic Monuments, Jean- François Lagneau as the main contractor.
The façades on the main courtyard and the Rue Saint-Antoine of the Hôtel de Sully, restored in the 1950s and 60s by cement screed works, were crumbling. They were also dirty because of pollution. The degraded façades and sculpted elements therefore required major restoration work, mainly cleaning and being made safe.
What were the challenges and constraints at this site?
This work, essential for the presentation of the building and people's safety, took place in a restricted space on an occupied site, i.e. in the presence of the personnel and the public. The latter had to endure the inconvenience related to noise and dust for a year as well as the constant obstruction of scaffolding, etc.; we had to explain why such constraints were inevitable. Tours of the building work helped people to understand better.

Il s'agissait également de remplacer les rideaux et revêtements muraux de tissus usés, de nettoyer les trois verdures du XVIème siècle de l'antichambre et de réintégrer du mobilier d'origine et/ou issu de collections extérieures.
Pour mener à bien ce chantier, l'architecte en chef des monuments historiques a fait appel à de nombreux intervenants, associant ébénistes, maçons, restaurateurs de peinture, tapissiers, ingénieurs en laboratoire. Ces intervenants recourent aux savoir faire les plus ancestraux comme aux techniques les plus sophistiquées.
