Old Ramschwag Castle, Häggenschwil

Old Ramschwag castle ruin, Häggenschwil, Switzerland, was erected in the medieval period by local lords who held their position in service to the Abbey of St. Gallen.

The origin of the site’s name has been debated. One proposal links the first element to a word for raven combined with a term for standing water, and notes that the castle was also once called Rabenstein. A second suggestion derives the name from an old word for wild garlic. A third reads the name as the estate of a man called Rambert, Bertram, or Wolfram, the personal name itself containing the raven element. Construction dates proposed for the fortress vary: its simple stone-cutting style has been read as consistent with building soon after 1200, while other estimates place initial work between the tenth and twelfth centuries. An individual named Ulrich de Rammiswag appears in a document from Konstanz in 1176, and the castle enters the written record in 1370 when Rudolf von Rosenberg‑Zuckenriet acquired it by marriage.

Throughout the later medieval era the castle’s owners acted as vassals of the abbots of St. Gallen. Rudolf von Rosenberg‑Zuckenriet, who became a citizen of St. Gallen in 1398, maintained a stance of neutrality that preserved his holdings. Relatives named Heinrich Walter and Eberhard von Ramschwag were recorded as taking action on the abbey’s side during armed conflicts. In 1427 Rudolf sold the property to Ulrich and Burkard von Helmsdorf; the Helmsdorf family retained possession until about 1490. Toward the end of the fifteenth century the site suffered landslides that made parts of it dangerous to live in. The castle was then transferred to a farmer, Hans Rudolf Koller, who removed and sold movable materials, notably timber from upper floors.

In the early twentieth century the ruin was rescued from further decay. In 1930 an architect named Müller and a builder named Thaler, both associated with the Swiss castle preservation association, purchased the site and carried out conservation work with the association’s support. Excavation carried out in connection with repairs revealed previously unknown foundations for living and working buildings and produced finds such as stone balls, arrowheads, metal fittings, oven tiles, pottery fragments, and animal bones. The conservation work continued through 1932. Funding for the 1930s effort amounted to nearly 20,000 Swiss francs; recorded contributors included a local Burgfonds, three private donors, and the federal government, and a plaque placed on the restored gate records that the ruin was saved with help from federal, cantonal, association, and private sources and placed under national protection.

The Thaler family kept ownership until selling the ruin and surrounding forest to the municipality of Häggenschwil on 26 March 2013 for 35,000 Swiss francs. A falling stone in 2022 prompted an extensive program of repairs carried out from mid‑March to mid‑November. One account lists the cost at 665,000 Swiss francs, with contributions from the federal government and the Canton of St. Gallen, public donations including crowdfunding, and the municipality; another report places the cost at about 600,000 francs and records the use of roughly 60,000 kilograms of mortar lifted by 210 helicopter flights and some 5,000 hours of labour. After these works the ruins have been described as among the best preserved between Lake Constance and Wil. In spring 2024 a spiral staircase and an attached viewing platform were installed in the main tower at a cost of about 150,000 francs, supported largely by donations, and an information panel with a reconstruction drawing was mounted by the cantonal archaeology authority.
