The history of Château de Mont dates back to the 15th century. Claude, daughter of Guillaume de St-Triviers, Baron of Mont-le-Grand, appears to have been the first to settle permanently in the current north wing, as evidenced by her coat of arms near the entrance.

In 1553, the Bernese period began with the Steiger family, who would hold the barony for a long time. A vault bearing their arms and the date 1696 remains in the castle. The Vaudois Revolution of 1798 led to the bankruptcy of the last lords. After several changes of ownership, the estate was finally offered in 1911 to Ernest Naef, from Geneva. Charmed by the site, Ernest and his wife acquired it and undertook its restoration while respecting its historical character.

In 1912–1913, the architect Fatio built the terrace pavilion, later celebrated by the poet Pierre Girard. In 1922, René Martin created the frescoes on the second floor. The castle also hosted the writer Czeslaw Milosz in 1954. The future Nobel Prize winner in literature found inspiration there for his work “The Captive Mind.”

Starting in 1934, the Naef family gradually expanded the estate. Today managed by Odile, Frédéric, and Marie Naef, it comprises 13 hectares of south-facing vineyards. Chasselas, Muscat, Gamay, Pinot Noir, Gamaret, Galotta, and Garanoir are cultivated there, thus perpetuating the long viticultural tradition of Château de Mont.
