Ecomuseum of the Pietra da Cantoni
The Ecomuseum of the Pietra da Cantoni is a territory-based museum in the Monferrato hills of Piedmont, dedicated to the distinctive local sandstone known as pietra da cantoni — a honey-coloured sedimentary rock quarried in the area since at least the 18th century and used to build the characteristic rural architecture of the Casalese and Ovadese districts. The ecomuseum documents the quarrying traditions, the skilled stonecutters’ craft, and the built heritage shaped by this material across villages, farmhouses, churches and road infrastructure throughout the region.

Overview
Unlike traditional museums housed in a single building, the Ecomuseum of the Pietra da Cantoni spreads across multiple sites in the Monferrato landscape — active and disused quarries, historic stone buildings, interpretation centres and open-air itineraries that guide visitors through the geology, craftsmanship and social history of the area. Pietra da cantoni is a fine-grained sandstone prized for its workability and warm appearance, and its use defines the visual character of settlements across Casale Monferrato and the surrounding hills. The ecomuseum is part of Piedmont’s wider network of ecomuseums, recognised for their role in safeguarding intangible and material heritage.
History
Quarrying of pietra da cantoni intensified in the 18th and 19th centuries as demand grew for building material to construct the farmhouses, palaces and churches of the Monferrato. Skilled stonecutters — known locally as cantunin — developed specialised techniques for cutting and dressing the stone, passing their knowledge down through generations. The decline of the quarrying industry in the 20th century prompted local communities and the Piedmont Region to establish the ecomuseum to preserve this intangible heritage before it disappeared entirely.
What you see
Visitors encounter historic quarry faces showing the extraction techniques of past centuries, interpreted with on-site signage and guided tours. Reconstructed workshops display the tools and methods of the cantunin trade. The broader territory reveals barns, estate farmhouses, rural chapels and road bridges built entirely from pietra da cantoni, offering an immersive lesson in how geology shaped local culture. An interpretation centre houses archival material, photographs and geological specimens.
Cultural significance
Pietra da cantoni is the defining material of the Casalese rural landscape — to understand it is to understand the social and economic history of the Monferrato. The ecomuseum model, supported by the Piedmont Region, treats the entire territory as the museum, recognising that heritage does not always fit within four walls. The site contributes to ongoing efforts to register Monferrato’s cultural landscape for broader international recognition.
Practical information
The ecomuseum is distributed across the Monferrato hills in Alessandria Province. The main interpretation centre and visitor starting point is located near Rosignano Monferrato. Opening hours are seasonal; check the official Ecomuseo della Pietra da Cantoni website or contact the Alessandria Provincial Tourism office before visiting. Guided itineraries can be booked in advance.
Getting there
The ecomuseum territory is best explored by car, as the sites are spread across the Monferrato hills between Casale Monferrato and Ovada. Casale Monferrato is reachable by rail from Turin (approximately 1 hour) and Alessandria (approximately 30 minutes). From Casale, local roads lead into the ecomuseum area. Walking and cycling itineraries are available for those wishing to explore the landscape on foot or by bike.
