Castle · Hidden Gem · Tourist Spot
Tourbillon Castle is a castle in Sion in the canton of Valais in Switzerland. It is situated on a hill and faces the Basilique de Valère, located on the opposite hill. The castle was ruined in a fire in 1788. It is a Swiss heritage site of national significance.
The Diocese of Sion was founded in Octodurum, now called Martigny in the early 4th century. In 589 the bishop, St. Heliodorus, transferred the see to Sion, as Octodurum was frequently endangered by the inundations of the Rhone and the Drance. Very little is known about the early Bishops and the early churches in Sion. However, in the late 10th century the last King of Upper Burgundy Rudolph III, granted the County of Valais to Bishop Hugo (998-1017). The combination of spiritual and secular power made the Prince-Bishops the most powerful nobles in the Upper Rhone valley. Sion became the political and religious center of the region. By the 12th century they began building impressive churches and castles in Sion to represent their power and administer their estates. Valère, as the residence of the cathedral chapter in Sion, was one-third of the administrative center of the powerful Diocese of Sion. In the 12th century the Cathedral Notre Dame de Sion (du Glarier) was built in the town below Valère hill. Glarier Cathedral became the seat of the Diocese of Sion, while the Prince-Bishop of Sion lived in the castle.

  • Good family walk up to the castle, there is not a lot up there but it's a little adventure getting up there and on a nice day you get a good view. Plenty of rocks for excited young kids to climb on.  more »
  • We went to Sion during our vacation in the canton of wallis in Switzerland. “Le Chateau de Tourbillon”was amazing! The castle ruins are pretty and a free guide told us everything we wanted to know  more »
  • Very cool historical location with great history and incredible views of the old city. A short, lightly strenuous "hike" to the top, bring a watery bottle as there are no resources at the top except a bathroom. Did not do the tour, instead studied the location before and after arrival.
  • Elegant views over valley, picturesque ancient ruins with some stores from history. Worth visit definitely.
