Propsteikirche St. Gertrud von Brabant, Catholic provost church in Wattenscheid, Bochum, Germany

The Propsteikirche St. Gertrud von Brabant is a five-nave Gothic Revival church built of rough grey-brown stone, with a steep dark slate roof and a large pointed-arch traceried window on the front facade. Its 65-metre Romanesque tower, older than the present church, is topped by four framed gable triangles; a slender green-copper spire rises behind the roof.

Bodenfunde belegen three church buildings on the hilltop site, the earliest a flat, unvaulted hall about 8 metres wide built around 800, likely one of the first parish churches on the Frankish-Saxon border. A 12th-century Romanesque basilica replaced it and burned down in 1435; a Gothic hall 18 metres wide followed, was raised after the town fire of 1635 and given its donkey-back roof after 1800. Rising congregation numbers led to its demolition and to Arnold Güldenpfennig's Gothic Revival church, built 1868–1872.

The patron saint is Gertrud of Nivelles, not the better-known Gertrude of Brabant; the name in the parish title follows local usage. The church stands on a hill ridge and was built as a fortified church (Kirchenburg) used as a refuge in times of danger. Its peal is the heaviest and most extensive in Bochum.

The church stands on a hill spur in central Wattenscheid, beside a paved square with trees; steps lead up to the entrance portal below the large tracery window. The 65 m tower is the oldest part, built in the 12th century, and the interior is entered at street level from the square.

Inside the building is an ancient stone baptismal font supported by four lion-shaped figures, over 1000 years old. The surface displays intricate hand-carved scenes depicting episodes from the life of Jesus.
