This long-term project is intended for a public wishing to participate in a vocational training action.

  The town of Gaillon was a border territory, disputed throughout the Middle Ages, between the Duchy of Normandy and the Kingdom of France, a first ducal castle is already attested in the eleventh century. The site was attached to the crown of France by a treaty in 1195; it then passed into the hands of various owners before being sold in the 13th century by King Louis IX to the archbishop of Rouen, who made it a summer residence. But the conflicts between the kingdoms of France and England resumed and the castle was again put in a state of siege and defense; its demolition was finally ordered in 1424 by the Duke of Bedford.

The current castle was built on these ruins from 1455 onwards by the archbishop of Rouen, who wanted to build an Italian palace. He thus made Gaillon the first Renaissance castle in France. Gaillon was embellished and enlarged over the years, then sold during the Revolution.

It became in turn a detention center (1812-1901), a garrison barracks and military training center (1901-1925) before being bought in 1970 by the State, which has since committed to restore and revive the castle.

This building was declared a Historical Monument by decree in 1862, followed by the gardens in 1965.

During this project, you will be trained, through different theoretical and practical modules, with the skills equivalent to those delivered in the CAP Mason for ancient buildings. 

Indeed, this site alternates practical sessions, on the site (masonry, stone cutting, assembly of a scaffolding, organization of a site area...), and theoretical sessions to deepen the knowledge acquired in the field (diagnosis of buildings, realization of plans, geology, operation of government services related to heritage, history of architecture...).

At the end of the training, a practical and theoretical white exam allows participants to assess their skills in relation to the professional title of bricklayer of old buildings.

Preservation, stabilization and restoration of the retaining wall

Vegetation removal, cleaning and joint removal

Removal of unstable elements (rubble and stones)

Remailing of masonry and jointing

Cutting and laying of replacement stone modules


Theoretical and practical modules

Open to individuals over the age of 18

The C.H.A.M association provides technical and educational supervision of the site.


This local project is supported by the Communauté d'agglomération Seine-Eure, the Fondation du Patrimoine, the DRAC Normandie, the Normandie region, and the Espace Condorcet, social center of the city of Gaillon.
