Schloss Heerbrugg

Balgach, Switzerland

---

Schloss Heerbrugg is a Baroque castle in Heerbrugg, part of the municipality of Balgach in Switzerland's canton of St. Gallen, built in 1775 by wealthy merchant Bartholomäus Schlumpf on the site of an ancient fort with remnants dating back to 1077 and possible Roman origins.

It overlooks the Aich River valley, evolving from a medieval stronghold through various noble owners like the Schobingers and Schmidheinys, who expanded it with a tower in 1911, before passing to private hands in 2005.

Recognized as a heritage site of national significance amid the Rhine Valley's castle landscape, it features preserved architecture, hosted summer concerts until recently, and stands as a symbol of the area's layered history from Roman times to industrial success via a 19th-century brickworks.
