Under the Aosta old parish church, archaeological diggings brought to light the early Christian cruciform basilica, indicated as Concilium Sanctorum, the Assembly of Saints because it was built on the tombs of some of the early martyrs who were buried in the Roman cemetery area which in itself was built on a protohistoric funeral settlement.
Inside you can see parts of the liturgical structures, the relic platform with the tombs of three bishops who lived between the 5th and 6th centuries (Grato, Agnello, Gallo) and other tomb chambers dating from between the 5th and 8th centuries.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
