The current edifice of Basilica of Sant'Abbondio rises over a pre-existing 5th century Palaeo-Christian church entitled to Sts. Peter and Paul, built by order of St. Amantius of Como, third bishop of the city. Erected c. 1 km outside the city's walls, it was intended to house several relics of the two saints which Amantius had brought from Rome.
The basilica acted as bishop's seat until 1007. Six years later bishop Alberic moved the seat within the walls. The basilica was then entrusted to the Benedictines who, between 1050 and 1095, rebuilt it in Romanesque style. The new edifice was dedicated to Amantius' successor, Abundius. The structures of the Palaeo-Christian church, discovered in 1863 during a restoration, are still marked by black and pale marble stones in the pavement.
The new basilica had a nave and four aisles. It was consecrated by pope Urban II on June 3, 1095.
The church has two notable bell towers rising at the end of the external aisles, in the middle of the nave. The sober façade, once preceded by a portico, has seven windows and a portal. Notable is the external decoration of the choir's windows. There are also Romanesque bas-reliefs and, in the apse, a notable cycle of mid-14th-century frescoes. Under the high altar are the Abundius' relics.
The medieval monastery annexed to the church, recently restored, will act as the seat of the local faculty of Jurisprudence.
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.
