The Church of St John dates from the twelfth century, the date of the nave, although the chancel is fourteenth century and the roofs and tower fifteenth century. It has a well-preserved Norman window. The building is of Old Red Sandstone. The church was restored in 1860-65 by John Prichard and John Pollard Seddon and again by G.E.Halliday in 1900–01.
Memorials to a number of members of the Raglan branch of the Somerset family, whose seat is nearby Cefntilla Court, can be seen in the church.
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.
