St. Maternus

The hall runs west to east: the portal and tower lie to the west, the choir to the east with a sacristy on each side. Inside and out, the structure is clearly articulated and free of ornamentation, with slender columns separating the three aisles of equal height. Immediately beside the church stands a detached rectory of yellow and red brick, built about twenty years later and likely also designed by Statz.

The stained glass windows were designed by Hanns Kirchner, who also created the rose window above the west portal in 1962; the choir places images from the Book of Revelation opposite scenes from the wartime bombing. The altars were designed by Elmar Hillebrand, with the encircling bronze relief on the high altar by Helge Kühnapfel. The Neo-Gothic Stations of the Cross came from the Moselle region, while the pews and confessionals are 19th-century originals; from Alt St. Maternus come a Madonna and Child from around 1470 and a Pietà.

The organ — 23 stops on two manuals and pedal — was built in 1869 by Steere & Turner for a church in Keene, New Hampshire; it was restored and installed in St. Maternus in 2011. The tower holds four bells. The 1927 bronze bell was the only one of the original set to survive World War II and has rung the Angelus at noon and evening again since a counter-pendulum system was fitted in 2007. The three remaining bells were supplied by the Bochumer Verein in 1949 as experimental cast-steel bells cast in a so-called Sekundschlagton profile.
