Discover Grosio: Rock Art and History

In Grosio, rock art, archaeological finds and historic buildings come together. The Rupe Magna and the Antiquarium showcase different types of early evidence; churches, castles and the Villa Visconti Venosta add perspectives on art and architectural history. When planning your trip, you can choose among different interests: prehistoric motifs, later buildings or cycling routes in the Valgrosina.

Rock Carvings and Archaeological Finds

The Rupe Magna is 84 metres long and 35 metres wide. It features more than 5,000 rock carvings dating from the end of the Neolithic to the Iron Age. The carved motifs include anthropomorphic figures, animals, geometric shapes and cup marks. Everyday objects such as rakes are also depicted. This variety offers specific motifs to focus on as you look: figures and animals, as well as geometric shapes and everyday objects.

The Antiquarium offers a different perspective on earlier settlements. Its permanent exhibition presents the results of archaeological excavations on Dosso dei Castelli and Dosso Giroldo. Most of the finds are ceramics from settlements whose origins and development date from the 16th to the 2nd/1st century BC—from the Bronze Age to the Iron Age. The focus here is therefore on both carvings on rock and objects from settlements as distinct evidence of earlier times.

Dosso Giroldo is also part of this subject. About 50 additional rocks bearing carvings were discovered there, north of Dosso dei Castelli.

Architectural History, Art and Collections

The Villa Visconti Venosta houses a museum with historic furnishings, old volumes, memorabilia and works of art from the collection of Marchese Emilio. The different types of objects give the collection a profile distinct from the archaeological finds at the Antiquarium: here, furnishings, books, personal mementos and works of art are brought together in a collection.

In the Chiesa di S. Giorgio in Grosio, the presbytery and apse feature a fresco cycle painted at the beginning of the 16th century. Depicted are the Last Judgment, stories of Saint George, Doctors of the Church and prophets. The motifs combine religious imagery with the architectural history of the church.

Castello Nuovo was built between 1350 and 1375. Its distinguishing features include a double defensive wall and a fortified inner tower, or keep. Despite its ruined state, it is considered the best-preserved and most interesting castle in the province of Sondrio. A Romanesque bell tower survives from Castello di San Faustino. The two sites thus offer different starting points for exploring Grosio’s architectural history.

Regional Products and Cycling Routes

Local food products are also part of the area’s offerings: Salumeria Macelleria Bordoni in Grosio sells bresaola and slinzega, traditional cured meats from Valtellina. If you are interested in buying them, check locally which products are currently available.

The Valgrosina has mountain bike and e-bike routes, including connections to trails such as Lagrosina. This offers a different focus from the historic sites in town: when planning your trip, you can consider cultural history and cycling routes as separate interests, without combining them into a single tour.

The historical subjects also span different periods: the rock carvings date from the end of the Neolithic to the Iron Age, while Castello Nuovo dates from the 14th century. The Antiquarium adds ceramic finds from settlements to this timeline; the frescoes in S. Giorgio and the Villa’s collection offer their own perspectives on art and history. You can choose the focus of your trip according to whether you are more interested in rock art, archaeological finds, buildings, collections or cycling routes.
