About The Fortified Monastery or Monastery Tower :
Built in the three periods over more than three centuries. It is made up of numerous parts including its cloisters and chapels.
In the 14th century, this fortress became the central tenet of monastic life, as shown by the transfer of the relics of St-Honorat to the Chapelle Ste Croix in 1391. In the following century, a first cloister was built around the same tower, then a second in 1477. Thus, at the end of the 15th century, the monumental centre of the abbey shifted to this Monastery Tower. From the 17th century, the upper floors were set aside for soldiers who came on the orders of the king to defend the coastline: a garrison hall, chambers and terraces with walkway used as a lookout.
