A sports ground with an outdoor and indoor pool, the Aquarena, was built north of the Bressanone Old Town. It is the result of a competition provided for the extension, which was to include a music school, underground parking and an indoor climbing gym; the latter has now been built. The climbing gym had to be of a certain height: a cube that is highly visible amongst the surrounding buildings thus emerged, which can also be viewed as a landmark. It not only affords good views of the city, but also allows one to see into the hall, and meets ecological considerations. The reinforced concrete structure, which has a steel-and-glass façade, also has a second façade level of corrugated gold-colored perforated plate elements that give the interior soft light without harsh shadows. The hall is accessed along a monumental staircase, which is also planned to serve as the entrance to the music school that will be built next door.
The multilayered design of the facade creates a Moiré pattern that constantly creates new impressions in the eyes of the beholder and a dynamic connection to the climbing hall for both the user and the outside observer.
