St. Paulinus, Catholic parish church in Lauterbach, Völklingen, Germany

St. Paulinus is a parish church in the Lauterbach district of Völklingen, designed by architect Peter Marx from Trier. The building displays a Romanesque Revival exterior with three towers, thick walls, and small windows, while the interior features a large barrel vault over a central space flanked by narrow side aisles.

Lauterbach's first church was built in 1860, when the village was still a branch of other parishes; it had belonged to Kreuzwald in Lorraine until 1802 and to Emmersweiler until 1852. Population growth around 1900 made that church too small, so Peter Marx of Trier designed a larger one. The foundation stone was laid on 2 July 1911, the church was blessed on 1 September 1912, and Bishop Michael Felix Korum consecrated it on 22 May 1919. Restorations followed in 1949–1951, 1976 and 1996.

The church is dedicated to Saint Paulinus, and the parish also calls it the "Warndtdom" after the Warndt region. The murals painted in 1922–1923 by Kiesgen of Speyer and Kaufmann of Munich show Christ as judge in the choir and, on the transept walls, four scenes grouping parishioners by age and profession. A Saint Barbara chapel occupies the right transept.

The church stands in the Lauterbach district of Völklingen, in the Warndt region near the French border. The main entrance is set in the west front, where a crucifixion group in high relief is carved into the tower wall; the three-tower facade can be viewed from the street at any time. Inside, the murals in the choir and transept and the two Baroque side altars from the late 18th century are the elements to seek out.

The nickname Warndtdom refers to the Warndt region, not to a cathedral rank. The 1931 Späth organ has 37 stops on three manuals and pedal, and was blessed on 26 July 1931. The current bells were cast in 1951 by Paccard in Annecy, France.
