Castle in Mont-Saint-Jean

The castle at Mont-Saint-Jean is a medieval fortress built with a rectangular keep and four corner towers linked by curtain walls. It sits elevated above the Serein River valley and remains a private residence today.

The fortress was first recorded in 924 and passed from the Vergy family to the House of Thil through marriage alliances during the 14th century. These transfers of ownership reflect the political shifts that shaped the region.

The chapel beside the fortress once served as the castle's private sanctuary and later became a parish church for the surrounding community. It shows how religious spaces evolved to meet changing needs over centuries.

The fortress sits on a raised promontory above the Serein River and can be viewed from outside, though it remains closed to visitors as a private property. The elevated location offers views over the surrounding landscape and allows you to observe the historic structures from a distance.

The former moats that once surrounded the fortress have been converted into walking paths that circle the entire structure. These paths allow visitors to explore the outer layout and scale of the stronghold up close.
