Festungsmuseum Heldsberg

Festungsmuseum Heldsberg, St. Margrethen SG

The Heldsberg artillery works was part of the border fortifications in the Rhine Valley. Due to its location, it controlled the eastern part of Lake Constance with its four 7.5 cm fortress guns in the north and the Rhine crossings in the Rhine valley.

The Heldsberg artillery works near St. Margrethen is a very special excursion experience. It was part of the border fortifications in the Rhine Valley from the Second World War until 1993. Due to its location, it controlled the southern end of Lake Constance in the north with its four 7.5 cm fortress guns and the Rhine crossings in the Rhine Valley as far as Montlingen in the south. The barrage at Stoss near Altstätten secured the crossing into the Appenzell region. The Heldsberg Fortress Museum now also includes the impressive underground command bunker of Border Brigade 8, Haslen AI, with over 30 rooms dedicated to the "Cold War" period.

In the Heldsbergstube and in the "Kästlis" Haslen soldiers' bar, you will be spoiled with drinks and food. Changing special exhibitions enrich the military history museums.

Important: The Heldsberg Fortress Museum, the Stoss barrage and the Grenzbrigade 8 command bunker in Haslen, AI are open to registered groups all year round. The minimum charge is now CHF 200.00 on all days.
