Summary
In 2003, restoration and new construction work in the private mansion of Mongenas, situated in the heart of Paris, brought to light a 14th-century bronze and jewelry workshop. Archaeologist Nicolas Thomas and his team from INRAP (Institut national de recherches archéologiques préventives) intervened to carry out a methodical excavation.
At the CRPA (Centre de recherche en physique appliquée à l'archéologie) in Bordeaux, archaeometallurgist Michel Pernot made a metallurgical study of the objects excavated. This makes it possible to understand the production techniques of that period.
