The Renaissance castle at the foot of the Calanda is the highlight of Haldenstein. When the roses flower in the spring, the castle garden is a visual and olfactory feast.
Haldenstein Castle was built in the 16th century and is included in Switzerland's inventory of art and cultural-historical protected items. The public castle gardens are one of the most beautiful attractions in the Chur region. Each year, these park-like gardens, surrounded by an impressive wall crowned with battlements, and the beauty of the blooms, bring joy to the hearts of the many visitors.
