The cultural heritage of the Valtournenche is most evident in the sacred art of the area: churches and chapels are the sign of a faith that has accompanied the lives of generations of local folk, and that remains very much alive to this day. Splendid examples include the Parish Church of Sant'Andrea at Antey-Saint-André, the bell tower of which was once the keep of an ancient stronghold, and the Parish Church of San Martino in Torgnon, which houses a superb museum with sculptures and wooden icons.

In Chamois, the parish church is consecrated to San Pantaleone and inside visitors can admire a splendid eighteenth-century altar. In Valtournenche, the Church of Sant'Antonio Abate is famous for the small Museum of Sacred Art inside.

Something else visitors to the area may find interesting are the remains of the ancient irrigation channels, known as "rus", which once took the water of the Marmore towards the arid slopes of the central valley; the arches of the "ru du pan perdu" are still visible above Antey.

In Petit Monde, at Torgnon, a traditional "rascard" dwelling houses an ethnographical museum in which visitors can admire traditional farming tools, as well as a faithful reconstruction of a traditional double bedroom.

The Valtournenche is also home to some of the best-known craftsmen in the Aosta Valley, whose works can be seen at the numerous craft markets that take place particularly in summer, such as “Lo pequie martzé de Votorneintse”, in Valtournenche, and the craft fair in Antey-Saint-André.
