This beautiful manor house was built in 1770 for Jean-Pierre Kurt d'Emersdorf, “Receveur des Domaines” (i.e. collector of revenue from Crown property) and “gruyer” (i.e. a public officer in charge of Crown forests) of the provostries of Virton and Saint-Mard, which were then under Austrian rule. In 1800, the estate was sold to the Bon family with a right of redemption.
This meant that the Emersdorf family had the right to redeem their property within a set deadline. They tried it with the help of Henri-Ignace Casaquy, an heir who presented himself on the very day of the deadline. This led to a lengthy lawsuit at the end of which the Bon family won the case. They kept the beautiful building until 1891.
During the World War I, Castle Bon was requisitioned by the occupant to accommodate German female staff who worked in the army administration.
