The platform was designed by the Chur architect Corinna Menn on behalf of the municipality of Flims and inaugurated in September 2006. It consists of a single pillar that is anchored in two places. The pillar, held back by a traction cable, protrudes into the gorge. On the pillar lies the triangular platform made of larch wood, which gives the structure the shape of a swift.

Lake Cauma, the Pearl of Flims Called "Lag la Cauma" in Romansh, which means "Lake of Midday Rest," Lake Cauma is the pearl of Flims. Origin This mountain lake was formed as a result of the largest landslide in the Alps, which occurred almost 10,000 years ago. The formation of the lakes is attributed to prehistoric landslides. The water seeped through the porous rockslide masses. However, it can also dissolve the limestone with the help of its carbonic acid. Over time, it created an underground passage. A deeper, impermeable clay layer ensures that the water does not completely seep into the ground. Text / Source: Flims Laax Falera https://www.caumasee.ch/geschichte/
