Festungsmuseum Heldsberg

The Heldsberg artillery factory near St.Margrethen is a very special excursion experience. From the 2nd World War until 1993 it was part of the border fortification in the Rhine Valley.
Due to its location, it controlled the southern end of Lake Constance with its four 7.5 cm fortress guns in the north and the Rhine crossings in the Rhine valley to Montlingen in the south.
The barrier at the junction near Altstätten secured the transition to Appenzellerland.
The Heldsberg fortress museum now also offers the impressive underground command bunker of Grenzbrigade 8, Haslen AI, which deals with the "Cold War" period in over 30 rooms.
In the Heldsbergstube and in the Soldatenstube "Kästlis" Haslen, you will be spoiled with drinks and food. Changing special exhibitions enrich the military-historical museums.
