Mario Botta’s Alpine spa sanctuary opens to mountain light
High in the Swiss Alps, Tschuggen Grand Hotel unveils the Bergoase Spa, a five thousand square metre sanctuary designed by celebrated architect Mario Botta. Glass sails rise from the mountainside, channelling natural light through four storeys of pools, saunas and restorative rituals inspired by the landscape itself.

The Bergoase Spa at Tschuggen Grand Hotel represents a rare convergence of architectural vision and mountainside setting. Mario Botta’s design places glass sails as the dominant feature, their geometry rising from the Alpine slopes to draw daylight deep into the four storey structure. Natural illumination floods the sanctuary, transforming the experience of spa ritual from something sequestered and artificial into something fundamentally connected to the surrounding peaks and sky.
Within this luminous envelope sits a composition of materials drawn from the landscape itself. Alpine granite anchors the spaces; flowing water moves through them as both visual and sonic element. The five thousand square metre complex accommodates indoor and outdoor pools, saunas thick with steam, and quiet zones designed for nothing but restoration. The architecture never announces itself as dramatic; instead, it recedes behind the primary purpose of the space: renewal through water, heat, stillness and air.
A philosophy rooted in science and landscape
The hotel’s Moving Mountains wellness methodology brings rigorous intention to the design. Treatments are tailored individually rather than prescribed as standard offerings. Natural ingredients and restorative rituals draw their inspiration directly from the Alpine terrain, the seasons and the particular geography of Arosa. This is not wellness as spa theatre, but as a deliberate engagement with the body and mind through environment and time.
The journey to Arosa itself becomes part of the experience: mountain air, narrow valleys, the particular quality of light at altitude. An afternoon spent moving between warm mineral water and cool Alpine stone, between enclosure and the panorama visible through Botta’s glass, offers a kind of restoration that belongs entirely to this place and this moment. The spa does not merely sit in the mountains; it belongs to them.
