A complete restoration for a plan classified as a Historic Monument.
Entitled “Plan des possessions des Célestins de Sens à Villeneuve”, it dates from the 18th century.
In 2022, it was discovered in a private residence and, due to its advanced state of deterioration, was entrusted to the Departmental Archives of Yonne for secure preservation pending restoration.
Methods and processes compliant with the specifications set forth by the Archives of France and tailored to the condition of the document were implemented, including meticulous cleaning, varnish removal, and consolidation of tears with appropriate Japanese paper, to ensure the long-term preservation of this cultural heritage.
A Degraded Condition of the Historical Document
During the analysis phase, numerous alterations were identified: dust, lacunas, tears, creases, and various stains. In general, the map was discolored and its varnish was cloudy. Temporary fixings (white strips) were present on the front, and the backing was too damaged to hold the plan together.
The Steps of a Comprehensive Restoration Process
All members of the team took part in the transfer of the document to a new cotton canvas, lined with an intermediate layer of 20 gsm Japanese paper, ensuring the reversibility of the lining operation.
