The Site During the Medieval Era (11th-16th centuries)

Découvertes archéologiques



During the renovation projects carried out on the museum, archaeological discoveries were made:


There were four archaeological survey campaigns led by the National Institute of Research and Rescue Archaeology between 2003 and 2005 in preparation for the worksites.


When work began in 2007, the fortuitous discovery of a bridge with four arches brought the archaeologists back to the site. Six more years of searching – between 2007 and 2013 – allowed them to excavate the front terrace and the back terrace.


At the end of these campaigns, we know now that the castle was not constructed from nothing, but that people occupied the site in the Middle Ages from the 11th to the 16th century: a Medieval curtain wall in 11th century, then a stronghold in the 14th century, a four-arch bridge at the end of the 16th century and the expansion of the castle basements in the 17th century.

These archaeological remains will be integrated into the visit of the future museum: come see them starting in 2016!
