Monastery of Santa María de Oseira became a monastery of the Cistercian order in 1141, an order of French monks sent by Saint Bernard of Clairvaux. The monks left in 1835 forced to leave by the government policies, abandoning it. They returned in 1929, this time being a community of Cistercians of the Strict Reform - commonly called Trappists. The monastery is popular stopping point on the pilgrimage to Santiago de Compostella.
The church was built between c.1200 and c.1239 AD. It is considered a landmark of Romanesque architecture in the Spanish peninsula. Its design was inspired by other pilgrimage churches. The main chamber is known as the 'palm tree room' and boasts a dome which is supported by four columns. It also possesses a Lapidarium: a collection of stone pieces obtained during the restorations and excavations. The buildings are in process of restoration by the state & monastic community. The monastery is a major state monument, and open to visitors.
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.
