The Château de Saint Brisson was a residence, presumably in the Saint-Brisson area in central France. It served as the home of Koll Azernal during his tenure as Presidential Chief of Staff to Federation President Min Zife, and was comparable in size and granduer to the presidential residence, Château Thelian. The château was not used by Azernal's successor, Esperanza Piñiero, who instead resided in a small chalet near Château Thelian. (ST novel: Articles of the Federation) Château de Saint Brisson was apparently not a historic structure, but rather built sometime after the early 21st century.
