The Catholic parish church of St. Peter in Ketten is a single-nave hall building with coffered ceiling, built in 1725 in the neo-Gothic style in the centre of Gau-Bischofsheim. The choir windows were designed by the well-known painter and glass artist Heinz Hindorf in collaboration with the glass workshop R. Münch. The weather vane on the church tower shows the church's namesake, St. Peter.
In the 1990s, the church was extensively renovated and refurbished.
The “Johann Geissel organ” in the church is the oldest church organ in Rhineland-Palatinate that is always played. National and international artists present their skills at the "Gau-Bischofsheim Organ Concerts".
The church is also available to fellow Protestants, who also celebrate their services there. The church can be visited during the day and is a worthwhile destination in Gau-Bischofsheim.
