In 1993/94 the "Sunnasaal" was built and awarded an architecture prize.
The Sunna Hall is designed as a cultural hall. School sports and cultural events take place here.
The elegantly designed hall with a view of the Walserkamm in the north and the Rätikon in the south is also very suitable for weddings with around 180 seats. The glass panes of the foyer can be opened so that the guest garden can also be included in events. Seated, the hall with the gallery can accommodate up to 300 guests.
The Sunnaal is hosted by the Gasthaus Sonne.
