Catacombs of Commodilla, on the Via Ostiensis, contain one of the earliest images of a bearded Christ. They originally held the relics of Saints Felix and Adauctus. The hypogeum leading to the catacombs was built in the fourth century. The catacombs were used for burials until the sixth century. Later, as happened to other Christian underground cemeteries, it was transformed into a place of worship of martyrdom: restoration of the basilica underground were made by several popes until the ninth century, a sign that the catacombs were still at that time a place of pilgrimage of devout Christians.
There were also found coins bearing the effigy of Pope Gregory IV (827-844) Pope Leo IV (847-855) finally gave the relics of the martyrs Felix and Adautto the wife of Emperor Lothair. Following the catacombs were abandoned and fell into oblivion. It was discovered in 1595 by archaeologist Antonio Bosio, but the first to identify it as that of Commodilla was in the nineteenth century, Giovanni Battista de Rossi. Restoration campaigns were performed at the beginning of the twentieth century and led to the complete excavation of the second level cemetery.
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.
