The Conciergerie was part of the Royal Palace for the Kings of France from the X to the XIV centuries. It then became a prison until 1914. Queen Marie-Antoinette was incarcerated there prior to her beheading. New layout and preservation work such as repointing necessitated the use of compatible materials. Saint Astier® Natural Hydraulic Limes were consequently specified.
