The castle of the Rojas is located on the top of a hill near the town of Poza de la Sal. At the end of the 9th century Count Diego Rodríguez Porcelos repopulated Poza building the castle for the defense of the new territory. Like other castles of this time it may have been a simple keep surrounded by some walls.
In the 14th century Rodriguez de Rojas family rebuilt the current castle. It was occupied in 1808 by French troops and was a target of continuous attacks of Burgos garrisons until the end of the war.
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.
