Mercier Castle, originally called Pradegg Castle, stands magnificently and sophisticatedly on a hill in the town of Sierre (French: Sierre). For half a century, the castle served mainly as a summer residence for the Mercier family until its donation to the canton of Valais in 1991. Since then, as required by the conditions of the donation, the castle and the adjoining park are mainly used for public, cultural and artistic purposes.

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.
