Architecturally, St Mary's Church was one of the most ambitious churches in the county. It is in the Decorated style with a prominent, integral, tower. The church was originally dedicated to St Leonard, until the mid-nineteenth century restoration. The porch, of the fourteenth/fifteenth centuries, has buttresses which display gargoyles and pinnacles.
The interior contains interesting, nineteenth-century, stained glass, including The Good Shepherd by Kempe & Co of 1930–31.
Next to the church stands The Procurator's House, a sixteenth house, now ruined, which belonged to the vicarage of Magor.
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.
