The parish church of Schönberg, completed in 1828 according to plans by the famous Prussian architect Karl Friedrich Schinkel, was badly hit by grenades at the beginning of the Battle of the Bulge on December 16, 1944, which made a new building necessary. This was inaugurated in 1962. Until the first mass in the new church, services were held in the Schröder Hall and then in a temporary church, which today serves as a parish hall.
The masonry of the new church is made of quarry stone, the tower is 20 meters high. The high colored windows were fitted with modern lead glazing. Inside the church, in addition to the windows and the Stations of the Cross, which were very modern at the time, the choir with the communion bench and the altar made of black Belgian marble are particularly striking, as is the 75 kilogram steel tabernacle, whose enameled doors are decorated with 35 rock crystals. Under the decorative sound button there is a wooden cross with a figure of Christ made of silver-plated copper from 1961.
In the back of the church in the baptismal chapel there is the Pieta of Schönberg, a figure of the Virgin Mary. It dates from the first half of the 16th century and was rescued from the castle chapel.
Another special feature of the church is the 19th century Holy Helpers Altar in the form of a winged altar (folding altar) in the choir. The winged altar is a special type of altarpiece common in Central Europe, where the fixed altar shrine can be closed off by several wings. The Holy Helpers Altar in Schönberg consists of two wings, two back panels and 16 paintings of the 14 Holy Helpers and two angels. The Holy Helpers were saints from the 2nd to 4th centuries. In the middle of the altar there is a statue of the parish patron St. George, which was created around 1850.
