Silum is an Alp located in the municipality of Triesenberg within the country of Liechtenstein. It is situated on a distinctive slumping mass composed of scree slopes, positioned beneath the breakaway ridge of one of the Alps' largest landslides. This geological formation occurred approximately 12,000 years ago following the retreat of the Rhine Glacier.
The area is characterized by traditional Walser agricultural patterns, which manifest as patchworks of meadows that reveal historic property boundaries through different mowing schedules during the summer. Ecologically, Silum features a variety of habitats including wetland areas, dry meadows that support rare plant and insect species, and wooded pastures that form semi-open pastoral landscapes.
