Probably built in the first half of the 12th century (although some legends say it was built in the 9th century), Sandiás Castle was located over a castrum (Celtic settlement). It participated in the Portugal secession wars (12th century). In 1386 it was assaulted by the duke of Lancaster, pretender to the Castile crown. In the 15th century it was demolished by a popular riot, and rebuilt later. It was a meeting point for troops in the wars with Portugal in the 18th century. There are many legends about this castle.
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.
