With the only thermal spring in Graubünden, the Therme Spa is a stunning landmark built from 60 000 stone slabs of Valser quartzite. Stone by stone. The combinations of light and shade, open and enclosed spaces and linear elements make for a highly sensuous and restorative experience. Only two years after its completion the Therme was listed as a protected building. It has been described as “a lesson in combining audacity with aesthetics“, “a totally unique, yet traditional spa and therapeutic centre that is the last word in peaceful sensuality“, and “a world first in spas”. The Vals quartzite quarried just two kilometres from where the building stands. The great slabs of the roof are grassed over: sections of flower studded alpine meadow.
