Entirely remodeled at the beginning of the 20th century in an opulent style inspired by the end of the 16th century, the Château de Congy seems abandoned. Surrounded by a beautiful landscaped park, it retains a dovecote and an interesting entrance pavilion from the beginning of the 17th century, with a cart arcade, pedestrian passage and side loopholes. Former possession of the Conflans family, the land of Congy belonged in the 16th century to Florentin de Béthune, gentleman of the chamber of the King of Navarre and guardian of the future Sully. The castle had in 1886 a stone staircase and a living room decorated with mythological paintings, probably dating back to Bénigne Chasot, president of the parliament of Metz, lord of Congy in 1704.
