Martvili Monastery sits upon the highest hill in the vicinity and was of strategic importance. The site upon the hill where the monastery stands today was used in ancient times as a pagan cultural center and was a sacred site. There once stood an ancient and enormous oak tree that was worshipped as an idol of fertility and prosperity. Infants were once sacrificed here as well. After the conversion of the native population to Christianity, the ancient tree was cut down so as not to worship it anymore. A church was originally constructed in the late 7th century upon the roots of the old oak tree and was named in honor of Saint Andrew who preached Christianity and converted the pagans across the Samegrelo region.
The main Martvili-Chkondidi Cathedral (Chkoni translates to 'oak') was reconstructed in the 10th century after invasions that destroyed the prior church. Preserved in the church are frescoes of the 14th to 17th centuries.
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.
