Basilica of Valère
Highlight • Religious Site
The castle and basilica of Valeria, named in honor of Valeriana, mother of the Roman city prefect Titus Campanius Priscus Maximianus, who is attested in 43 AD, are located on one of the two hills that the city of Sion on the eastern side of the old town tower above. Already laid out in Celtic times, the castle and church were first mentioned in a document in 1049. The oldest parts of the three-aisled basilica, divided into four bays, with a transept and two chapels flanking the choir, were built between 1100 and 1130 in the High Romanesque style. The tower above the north transept, the polygonal window floors above the semicircular apse and the barrel vault above the pillars were added later. In the 13th century, the nave and aisles were given a cross-belt vault, modeled on the Lausanne Cathedral. The rood screen separating the choir from the nave was also installed at this time. Laid out as a pilgrimage church of “Our Lady of Valeria”, the miraculous image, a Gothic marble statue of the Madonna with the baby Jesus from the beginning of the 15th century, forms the central element of the church. Today it stands high above the high altar. Pictures of apostles, prophets and national saints decorate the walls of the choir.

Tourbillon Castle
Highlight • Castle
Tourbillon Castle is a castle that has been preserved as a ruin and is located on the hill of the same name, northeast of the old town of Sion in the Swiss canton of Valais. Opposite the castle, the basilica of Valeria is enthroned on another elevation. Tourbillon was built by Bishop Bonifatius Challant at the end of the 13th century. The two hills and their buildings tower above the city by far and thus shape the cityscape and landscape.
In 1788 the castle was destroyed by the great city fire. Tourbillon has been classified as a historical monument since 1907 and has been listed in the inventory of protected monuments of national importance in accordance with the Hague Conventions since 1977.
Archaeological excavations show that the hill was settled as early as the 5th millennium BC.
In the Middle Ages it served as a sentry during wartime. This is also indicated by the remains of a donjon, which is located under the chapel built in the 15th century. Furthermore, a document lists around 1270 names of people who should have occupied the watchtower on the hill in the event of war. Bishop Bonifatius Challant initiated the construction of the castle in its current dimensions in 1297. Dendrochronological dating, however, showed that large parts of the complex were only built around 1307. The city of Sion was to be protected by the rebellious nobility under Peter IV von Turn.

It is not clear to me why a picture of the bishopric is on the title picture - the castle ruins offer enough corners worth seeing of their own. Definitely worth a visit. A guided tour is also offered, giving access to some rooms, e.g. the chapel.

An interesting old ruined castle, also called a castle. Unfortunately it burned down towards the end of the 18th century and was never rebuilt. As soon as you are near Sion, the castle catches your eye, so the castle hill is dominant. From the castle you have a good view of Sion and the bishopric.
