Museo a Cielo Aperto

La Thuile's answer to a conventional museum is the valley itself. The Museo a Cielo Aperto — open-air museum — is the municipality's official format for reading five thousand years of border history in the landscape: megalithic stones, Roman roads, mountain chapels, coal mines and war outposts, connected through a network of itineraries across the landscape.

Why it matters

The concept solves a real problem: La Thuile's heritage is scattered across hamlets, passes and hillsides, where no building could contain it. The official portal presents the museum with an image that captures the idea — a museum so large that the walls are the alpine peaks and the ceiling the sky, holding structures and traces across eight distinct historical epochs, from the Celtic cromlech at the pass down to the Second World War outposts, taking in the ancient terraces and the mining remains around the village. What the format delivers is narrative coherence: the same municipal portal that runs the ski resort's information frames the stone circle, the chapels, the fortifications and the mine trail as chapters of one story, so the landscape itself becomes the setting for a history of alpine border life across five millennia.

What to notice

Each itinerary provides a lens on a different epoch of the same small territory. The prehistoric and Roman layers concentrate at the Colle del Piccolo San Bernardo, where the cromlech, the Roman temple and mansio remains and the Joux Column are concentrated in the same landscape. The medieval and devotional layers thread through the valley floor: the parish church of San Nicola, documented since 1093, and the string of frazione chapels along the old road of the Gauls. The industrial layer lives in the woods of the Promenade des Mines, where rails, galleries and machinery record the coal economy that ended in 1966. The contemporary layer is military — Savoy trenches and Second World War bunkers on the heights. The museum format also draws attention to smaller features: miniature churches in each village, solid old fountains, ancient terracing, and the continuity of agricultural practice around them.

Context and history

The open-air museum is an institutional project, not a marketing label: it is presented on the municipality's official portal as the umbrella under which the territory's historical-cultural itineraries are collected and promoted, alongside the downloadable museum leaflet. Its logic rests on La Thuile's unusual stratification — the portal counts eight epochs of human presence in a single municipality, a density it attributes to the valley's position on one of the principal alpine crossing routes, decisive for the Roman Empire and every power after it. The named itineraries include the ancient places of worship, the fortifications, the Promenade des Mines and the Sentiero della Memoria. The Maison Musée Berton provides an indoor counterpart to this landscape-based heritage.
