Niasvizh Catholic Corpus Christi church was built in 1587–1593 according to the design of the Italian architect Giovanni Maria Bernardoni at sponsorship of Mikołaj Krzysztof Radziwiłł. The Jesuit church in Niasvizh was the first construction in Baroque in the whole territory of Rzecz Pospolita.
The temple interior is richly decorated with paintings. The frescoes were performed in 1750-1760s with participation of the artist Ksawery Dominik Heski (restored in 1900–1902). The frescoes embrace 40 individual compositions depicting Saints, allegorical scenes and biblical stories. The fresco compositions include cartouches with the Bible stanze and references. There is K.D. Gesski’s picture 'The Lord's Supper' (1753) in the main shrine. In addition to the paintings, the church interior contains a lot of plastic images, i.e. bás-reliefs and bust gravestones of the 17th – 19th centuries, marble altars and monuments.
There is a choir with an organ above the temple entrance. An entrance into the family crypt – a burial vault of the Radziwills – is located next to the bás-relief under the altar of Christ. There are over seventy burials of the mighty dynasty in the semi-basement.
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.
