In 1948, the municipality acquired the listed property from the Stockalper family. The Stockalper Castle captivates with its peculiar and highly representative design. The three towers, named after the Three Kings (Kaspar, Melchior and Balthasar), are striking. The courtyard with the old stagecoaches can be visited free of charge. The castle complex is complemented by the Stockalper Garden. The garden was renovated in 2002 according to plans by Prof. Kienast and, in keeping with Stockalper's three-part design, comprises an accessible ornamental garden, a tree garden and a vineyard whose grapes are pressed annually. In honour of the Three Wise Men from the Tomorrowland a special mass is said in the castle chapel on their name days.
The castle also houses an interesting permanent exhibition ("Passage Simplon"), which tells the story of the town closely linked to the pass. It can be visited free of charge from May to October / Tuesday to Sunday (see opening hours). To visit the rooms in the castle, you can take part in an open or special guided tour.
