The Castillo Palacio de Marcilla is a Gothic-style castle built in the 15th century by Mosén Pierres de Peralta. At first it had a defensive character but when the Marquisate of Falces was instituted it became the residential palace of the Marquises. The gateway to the castle, which houses the drawbridge under which the moat runs, is next to what is considered to be the Homage Tower, one of the four towers that make up the corners of the castle. Inside the fortress there was a large parade ground around which the rooms and rooms were distributed. The palace chapel preserves its 16th century paintings.
Acquired by the Government of Navarra in 1976 and thoroughly restored in the 2008-2012 period, it currently houses the town hall and other municipal bodies.
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.
