The Propsteikirche is the main Catholic parish church of central Dortmund, standing on Propsteistrasse just west of the Marktplatz. Its origins go back to the Dominican order, who founded a church here in the thirteenth century; the building that stands today is a postwar reconstruction in a stripped modernist style, with the deliberate visual incompleteness of its tower serving as an architectural act of remembrance.
The interior is quieter and more contemplative than the older Protestant churches nearby. A few salvaged medieval fragments — carved stonework, a small altarpiece — are incorporated into the new space as traces of what was lost. The church functions as an active parish and is open to visitors outside of services.
