Sulzberg Castle

Sulzberg Castle is a medieval fortress located in Untereggen in the canton of St. Gallen, featuring traditional Swiss castle design with regional architectural elements. The structure includes both a main building and surrounding grounds that remain visible today.

The fortress was built in medieval times as a defensive structure and shaped the settlement for many generations. Its preserved form shows how it evolved from a pure defensive stronghold into a regional cultural site.

The castle has developed over centuries as an important place for the region and continues to shape how Untereggen looks today. Its presence connects the village to its medieval past.

The castle stands in Untereggen and can be viewed from the outside, with some areas also accessible from within. Good paths lead to the site, and it is worth exploring the entire surrounding area.

The structure is also locally known as Möttelischloss, a name that appears in regional records and underscores its deep connection to the place. This alternative name reveals more about local history and how residents have understood the castle over time.
