Burg Grimmenstein

Burg Grimmenstein is a castle ruin perched on a strategically positioned hilltop in St. Margrethen, consisting of various medieval structures. Visible today are sections of a residential tower, an ancient cistern, and substantial wall fragments scattered across the site.

The structure originated in the first half of the 13th century under the direction of St. Gallen abbot Berchtold von Falkenstein. After a change in its use, the castle was destroyed in 1416 and has remained a ruin since.

The ruins serve as a regional landmark showing how medieval fortifications were built and functioned in this area. Visitors can observe the remains and understand the role such structures played in local life.

The site sits on elevated terrain and can be reached on foot via a hiking path that offers varying difficulty depending on the route chosen. Sturdy footwear is recommended as the ground is uneven and can become slippery after rain.

In the 14th century, the fortress transitioned from an aristocratic residence to a hideout for bandits, marking an unusual turn in its history. This chapter ended with the structure's demolition in the early 15th century.
