Uvdal Stave Church was originally constructed just after the year 1168, which we know through dendrochronological dating of the pine tree used during the construction. The logs were not completely dry when the construction took place. The church was made on top of the remains of previous church on the site, thought to have been made with the use of imbedded corner column technology at the beginning of the 11th century. This we know from an archeological excavation that took place during 1978. Churches made during the 12th century were usually very small, perhaps no more than 40 square meters in their footprint. They were therefore often expanded, even during the Middle Ages and certainly just before and after the Reformation, which took place during 1537 in Norway.
The nave of the church was first expanded to the west during the Middle Ages, when the original apse of chancel was also removed and the chancel itself elongated. Again, during that period, an extra center column was added to construction. The chancel was torn down again in 1684, when a new and wider chancel was made. This had the same width as the nave. Then, during the period 1721–1723, the church was made into cruciform. A new ridge turret had to be made, to fit the new cruciform. Later, in 1819, a new vestry was added to the north wall of the chancel. The exterior walls were panelled in 1760.
Benches with ornately decorated sidewalls were added to the nave in 1624. The oldest part of the interior was probably richly ornately decorated by painting during 1656, the expansions during 1684 and 1723. Two scary halfmasks are quite visible on the poles of the chancel, and according to myth they were able to capture demons.
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.
