The stone is engrained in the castle, it defines it and shapes its architectural parts. It is a magnificent white stone, hard, compact, worked with mastery with a “boucharde” to give it a natural finish, with decorative elements and perfectly square blocks. It is the principal feature of this building with its weight-bearing and decorative forms. It is thanks to this material that the castle has remained structurally intact over time. It is the stone that gave birth to the structure, and gives body to the wall surfaces, emphasized by its design.
