The rocky heights above Brienz Lake were first occupied and fortified by the Late-Bronze Age. During the Middle Ages, the land around the castle was owned by the Barons of Brienz and Raron. Around 1231, they moved to Ringgenberg village and soon thereafter into the castle. Ringgenberg Castle was probably built in several stages during the 13th century. It first appears in the historical record in 1240.
During the 13th century, the Counts of Ringgenberg expanded their power, often at the expense of Interlaken Abbey. The ruin of the estate began in the time of Philipp von Ringgenberg (1351–1374). In 1351 part of the estate was sold to the Abbey. In 1381 Ringgenberg castle was burnt and plundered by troops from the Canton of Uri and Count Petermann von Ringgenberg was taken in chains to Obwalden. In 1386, the castle and lands were assigned to Bern. However the city lacked the funds to rebuild the burned castle and in 1411 and 1439 parts of the castle and village were sold to Interlaken. A few years later, in 1445, Bern reacquired the land, but lost it again in 1457.
In 1528, the city of Bern adopted the new faith of the Protestant Reformation and began imposing it on the Bernese Oberland. Ringgenberg joined many other villages and the Abbey in an unsuccessful rebellion against the new faith. After Bern imposed its will on the Oberland, they secularized the Abbey and annexed all the Abbey lands. Ringgenberg became a part of the Bernese bailiwick of Interlaken.
The church was built in the ruins of Ringgenberg Castle in 1670 under the architect Abraham Dunz. Dunz incorporated the castle walls and one of the wall towers into the new village church.
The castle ruins were repaired and renovated in 1928, 1946–49 and 2006–08.
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.
