The foundation stone for St. John's Church was laid on October 7, 1954 and the church was consecrated on September 2, 1956. In addition to the congregation and the regional church, the "Wooden Church Crusade" association founded in the USA in 1950 also contributed to the construction of the church. This association had set itself the task of promoting the construction of a simple church for each of the then 48 US states in the area of the inner-German zone border after the war.

The large parabolic opening on the gable wall, which is repeated in the bell tower, is a distinctive external feature. The interior also has the shape of a parabolic bowl. The inverted parabola symbolizes the opening hands of God, which on the one hand provide protection and on the other represent an inviting gesture. The building is relatively small - 28 meters long and 10.5 meters wide - and the interior is deliberately kept simple in order to draw the visitor's attention to the altar. The crucifix was created by Wilhelm Keudel, an artist from Salzgitter-Gitter, and the altar windows with motifs from the Revelation of St. John were designed by Hamburg graphic artist Claus Wallner, who also designed the other church windows. The organ opposite the altar, a work with 17 stops and a Rückpositiv, was created by the Goslar master organ builder Blöß.

The bell tower next to the church is around 25 meters high and houses the church's three bronze bells. They bear inscriptions from the Prologue of St. John. The first bell reads "In the beginning was the Word and the Word was with God", while the second bell continues with "and we saw his glory". The inscription on the third bell ends with "and from his fullness we have all taken grace for grace".
