Valère Castle, Fortified church in Sion, Switzerland

Valère is a fortified church perched on a hill overlooking Sion, housing multiple buildings and courtyards within its walls. The compound mixes residential spaces, religious structures, and defensive elements arranged across the slope in a compact arrangement.

Valère is first documented in 1049 as the site of the cathedral chapter of Sion. The church was built in Romanesque phases from 1100 to 1130, then expanded between 1235 and 1267 with two aisles and a Gothic ribbed vault over the choir. The chapter resided here until the French invasion of 1798.

The name Valère derives from Valeriana, mother of the Roman city prefect Titus Campanius Priscus Maximianus, attested in 43 AD. The church was built as a pilgrimage site to Our Lady of Valeria; its Gothic marble Madonna and Child, made in the early 15th century, stands above the high altar. Later, Saint Catherine of Alexandria, second patron of Valais, was venerated here.

The climb to the hilltop is steep but the paths are well-marked and the city views reward the effort. The basilica interior is open to visitors, and you'll also find the regional history museum within the same grounds.

The organ on the west wall, built around 1435 and enlarged by four stops in 1687, is among the oldest playable organs in the world. Its pipes form a rough church outline: two towers and a triangular roof. Forgotten in the 19th century, it was revived by conservator Maurice Wenger in the 1950s and since 1969 sounds each summer at the Festival de l'orgue ancien de Valère.
