Ev. Pfarrkirche Herdecke, Protestant church building in Herdecke, Germany.

The Ev. Pfarrkirche Herdecke is a Protestant church featuring a striking neo-Romanesque western tower built between 1902 and 1903 using locally quarried Ruhr sandstone. The structure contains five bronze bells cast in 2004 and continues to serve the religious needs of its congregation.

The site originated as a Benedictine monastery founded around 810 or 819, with the earliest written record dating to 1214. The present church building was constructed in the early 1900s, replacing earlier religious structures that had stood on this location.

The church keeps the name of the former collegiate foundation: the settlement was first recorded as "Herreke" around 1183/87, and the foundation was tied to the Virgin Mary from 1240. After 1666 it was a simultaneous foundation, with every fourth abbess Catholic and a quarter of the funding reserved for Catholic sisters. Services, concerts and events are held only occasionally, and the doors are almost always closed to pilgrims and tourists.

The church is usually closed to pilgrims and tourists; services, concerts and events are held only occasionally. The old cast-iron bells are displayed outside on the ground behind the central apse, and a row of historic gravestones stands in the north-west part of the grounds.

Archaeological digs conducted between 1937 and 1939 uncovered multiple building phases of the earlier monastery, though researchers could not pinpoint the exact age of the original structures. These findings show that the site underwent repeated changes and renovations spanning many centuries.
