Cathedral of Our Lady of Sion

Notre-Dame du Glarian cathedral, Sion / Sitten
Cathedral of Our Lady (Sion)
Towards the end of the 5th century, the bishopric was moved from Martigny (Octodurum) to Sion. However, not even the location is known of a Sion episcopal church before the 8th century. At the turn of the 9th century, the first building on today's site was a Carolingian church, which was destroyed by fire in 1010. Then the Romanesque cathedral was built, which lasted until the 15th century with a few changes. The core of the bell tower, which still exists today, was built around the turn of the 13th century. In the heyday of the secular power of the bishops of Sion, the castle and basilica of Valeria were the seat of the cathedral chapter and representative of the prince-bishopric. However, the cathedral dignity remained with Notre-Dame du Glarian.
Several fires and acts of war in the late Middle Ages damaged the Romanesque building so badly that the nave was built between 1450 and 1500 under the bishops Walter Supersaxo (1457–1482), Jost von Silenen (1482–1496), Nikolaus Schiner (1496–1499) [3] and Cardinal Matthäus Schiner (1499–1522) was replaced by a new Gothic building which, together with the Romanesque tower, essentially forms today's cathedral]
In 1947/48 the choir was extended by two yokes to the east.
The Cathedral of Our Lady of Sion is an east-facing three-aisled basilica with a transept and an elongated choir. The massive Romanesque tower with a cone point dominates the cityscape.
In the portal tympanum there is a fresco in the style of the northern Italian Trecento; it shows the Mother of God, surrounded by two holy bishops and donor figures. The most important piece of equipment, the late Gothic altar triptych, represents the root of Jesse.
View of the organ
The organ was built in 1988 by the organ builder Hans Füglister. The organ case comes from an instrument made by the organ builder Casper Carlen in 1786 and was created by Matthäus Carlenin; pipe material from the instrument is still present in today's organ work. The original two-manual instrument was reworked in 1874 by the organ builder Joseph Merklin and its disposition was changed. In 1912 the organ was redesigned and enlarged by the organ builder Henri Carlen von Glis. a third manual. In 1988 the organ was restored and partially rebuilt for the last time. Some of the pipe material dates back to 1912. The slider chest instrument has 49 stops on three manual works and a pedal. the actions are mechanical.
