The castles of Sion

What might the small city of Sion look like without its two castles? The striking fortifications on the Valeria and Tourbillon hills and the Majorie and Vidomnat buildings form part of the medieval built fabric of the Valais canton’s capital. They evoke a time when Catholic bishops and the cathedral Chapter controlled the gateway to the Great St Bernard and Simplon passes – two major historic trade routes across the Swiss Alps. Discover Sion’s medieval atmosphere, and its treasure of the rarest and unique artefacts.
