The region joined the Roman Empire. In 47, Emperor Claudius founded Forum Claudii Augusti, later renamed Forum Claudii Vallensium to avoid confusion with an other city that was dear to him. Octodurus was the principal town of the area until the displacement of the episcopal see to Sion in the 4th century.

The city is also famous for its museum, the Pierre Gianadda Foundation, built on top of Roman ruins. The foundation hosts three painting exhibitions every year, with works by renowned masters. It also has a permanent automobile and Gallo-Roman exhibitions.
