During the 15th century, the small priory began to lose importance until the office of prior was reduced to a title without power.

In 1484, by papal decree, leadership of the priory was transferred to the college of canons of the Munster of Bern.

[2] In 1535 Bern sold the Herrschaft of Münchenwiler to the former Bernese Schultheiss Hans Jakob von Wattenwyl.

Following the 1798 French invasion, Münchenwiler became part of the Helvetic Republic in the short lived Canton of Sarine et Broye.

The von Graffenried family became impoverished in the early 20th century and in 1922 they began to sell some of their property in the area.
