Montby Castle is a former fortress and manor house built in the 14th century by the eponymous family, replacing an 11th-century structure on the Montby plateau.

The association "Les amis de Montby", which contributes to the preservation, restoration, animation and promotion of the castle, invites you to visit this medieval castle, which is currently being restored, by appointment.
Some 1st Saturdays of the month are devoted to "Site Saturdays" at the castle to continue its development and restoration.
Since December 2009, it has been listed on the Inventaire Supplémentaire des Monuments Historiques (Supplementary Inventory of Historic Monuments).

The oldest walls of the castle date back to the Middle Ages and are one metre eighty wide. The local inhabitants helped to build this fortified house with its large square tower, where they and their livestock took refuge in times of invasion.
The castle was taken, pillaged and burnt down several times, and the inhabitants are said to have taken refuge in the nearby caves. In 1795, it was put up for sale as national property, and then became a farmhouse.
The 1870 war did not spare it, as one of the 4 wings, the Levant wing, was burnt down and never rebuilt.
Despite all this, Montby retains an inalienable treasure: a magnificent view over the Doubs valley and the Lomont mountain range...
