50 Abandoned Hotels That Are Frozen in Time

46. Hotel Adler – Switzerland

Once a thriving spa destination nestled in the Swiss canton of Valais, Hotel Adler welcomed guests seeking alpine serenity and healing waters. Built in the early 20th century, its Belle Époque charm drew dignitaries and the European elite. But with the rise of modern resorts and waning interest in traditional thermal therapies, it quietly faded. Today, its stone balconies overlook an empty valley, while its grand dining hall—still adorned with faded frescoes—sits eerily silent. Snow drifts pile at its doors each winter, sealing it shut like a forgotten storybook. In the stillness, it’s as if the Alps themselves are holding their breath.
