Great St Bernard Hospice

The church of Bourg-Saint-Pierre would have been built around the year 1000 by Hugues, bishop of Geneva. The Romanesque building was destroyed and rebuilt over the years. The current Baroque building was built in 1739, keeping the old bell tower, which is the oldest in the Valais. This bell tower has a carillon consisting of six bells melted down and installed by the Rüetschi foundry in Aarau in 1932.

The present Aosta Cathedral was built in the 11th century, probably at the request of Bishop Anselmo (994-1025), and was probably designed in the Nordic style, inspired by the main church complexes of the Germanic Empire in the Ottonian period. During the 12th and 13th centuries, the church underwent transformations and embellishments. In the 15th century, the church was completely transformed, especially inside (burial chapel, sanctuary, choir). At the end of the 15th century and the beginning of the 16th century, a series of works on the body of the building gave it the appearance it still has today, such as the Renaissance-style façade built between 1522 and 1526.

The Church of Our Lady of the Visitation was erected between 1670 and 1680 on a site where churches have been built since the 4th century. The bell tower, built in 1717-1719, is one of the most elegant in the country and the highest in the canton.
