"Originally built ca. 1913 as an alpine sanatorium in Zuoz, the 68-room Hotel Castell offers a full-on immersion in art. Its owner—the Swiss artist and collector Ruedi Bechtler—has invited a number of big-name artists to develop projects on site, from Pipilotti Rist (who designed the Red Bar with Zurich architect Gabrielle Hächlero) to Tadashi Kawamata (see sun terrace and pool) to James Turrell (you’ll want to spend some time sky-gazing in his open-air installation, Skyspace Piz Utèr)."
