The east wing of Gram Castle was built in the beginning of the 16th century. The builder is unknown, but was probably one of the Reventlow family, who owned Gram from about the middle of the 15th century until 1560. The south wing was built by the Commander Hans Schack (1609 - 1676) a few years after he bought the manor in 1664. The west wing of the manor was built 1752 by Countess Anna Sophie Schack (1689 - 1760). Today it is a conference center.
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.
