Acquired in 1553 by the Steiger family, last dynasty of the lords of Mont, the seignory remained in hands of this family until the Revolution. At that time, the field was sold to Joseph Bouër, a financier, member of the Council of Geneva, and originating from France. His wife accommodated many Genevese peoples when their city was threatened by the French army, which involved a very animated life in Château de Mont.
