St. John's Church (Sint-Janskerk), named after St.John the Baptist, was originally built as a baptistery for the St. Servatius Chapter of Maastricht. In 1633, after a period in which it functioned as an autonomous parish church, it came into the possession of the Dutch Reformed Church, established in 1632. This as a result of the capture of Maastricht from the Spanish army in 1632 by the troops of the Seven United Provinces of the Netherlands under the command of Prince Frederik Hendrik of Orange. After the establishment of a state-church, i.e. the Dutch Reformed Church, all catholic churches had become protestant in the regions already conquered.
The Prince Bishop of Liège, the Duke of Brabant and Prince Frederik Hendrik agreed that in Maastricht in principle only smaller chapels should be handed over to the protestants. The bigger churches remained catholic, which was exceptional from a national point of view. However, already in 1633 the protestant chapels proved to be too small and after new discussions two churches, one of which was St.John's, came into the possession of the protestants. The first service of the Dutch Reformed Church took place on the 1st of January, 1634.
Since 1987 the church has been in the use of the 'Protestantse Gemeente St. Jan', a federation of two different reformed communities.
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.
