Nestled among the mountains near Tirano, Sernio is a small village that preserves a unique heritage: the Baitelli (in the local dialect “baitei”), ancient dry-stone structures that tell stories of ingenuity, survival, and harmony with nature.
Walking among the Baitelli is like stepping into an open-air museum where every stone speaks of the deep connection between humans and the Alpine environment. These distinctive, self-supporting stone buildings date back to very ancient times (as early as the 15th century BC, with origins traced even to archaic Greece) and were constructed without mortar, showcasing extraordinary craftsmanship with concentric rows of perfectly interlocking stones.
The Baitelli were born out of two fundamental needs of mountain farming: clearing fields of stones (a process called “spietramento”) and creating covered, practical, and durable spaces. Today, these structures dot the Sernio landscape, transforming it into a fascinating cultural environment where human intervention blends seamlessly with nature.
In recent years, thanks to a project promoted by the Tirano Mountain Community, several baitelli have been restored and enhanced along the scenic “Sentiero del Sole” (Path of the Sun)—a hiking trail crossing emblematic sites of mid-Valtellina, once abandoned after World War II but now rediscovered and opened to the public.
Hiking this trail, you’ll traverse the southern-facing slopes of the Rhaetian Alps at mid-altitude, between Sondrio and Tirano. The trail’s name derives from its prime sun exposure, enjoying sunlight year-round.
