The castle of Dammartin (or Froissard), listed as a Historic Monument since 2011, was built in the 16th century by the Mairot de Mutigney, a family of parliamentarians in the parliament of Franche-Comté. It was profoundly transformed in the middle of the 18th century by the prior of Mutigney, canon of the Besançon chapter and archdeacon of Faverney, poet and numismatic. Following a resounding trial, his brother became captain of Mutigney, then his daughter, Félicité, who brought him to the Froissard de Broissia by marriage in 1771 to Hilaire-Flavien marquis de Broissia. The castle of Dammartin was preserved until 1918 in this same family.
The house has a rectangular plan, centered by a triangular pediment and a large horseshoe staircase has a tower at the south angle, and the row of lounges opens to the south-east by large crusades on the park. An alley of charmilles connects the house and the common building while another borders the park to the southwest.
The castle of Dammartin represents a typical example of a house of pleasure of the parliamentary aristocracy Franc-Comtoise which has kept almost all its interior architecture of the middle of the eighteenth century.
