St. Mariä Geburt, Gothic church in Stammheim, Germany.

St. Mariä Geburt is a neo-Gothic hall church with a central nave and two side aisles, built in 1902–1903 around the old tower and choir, which now form the transept. The apse faces north because the original chapel was oriented west-east. The walls are of ring-oven brick, tracery of Weibener tuff, and interior columns of Kyllburg sandstone.

The Stammheim chapel received its first written mention in 1075, with the current Marian chapel constructed in the early 14th century. The church underwent major expansion in 1902, creating the three-aisle hall church structure that visitors see today.

The 16th-century image of the Joyful Mother of Stammheim made the church an important Marian pilgrimage site. Pilgrimage seasons are the feast of the Ascension and the octave around 8 September, when the patron saint of the Archdiocese of Cologne is venerated. Processions to Stammheim are documented since the 17th century.

The church is oriented unusually: the old west-east chapel became the transept, so the new apse faces north and the main portal sits at the south end of the nave, beneath the organ gallery. The side walls are braced outside by stepped buttresses and pierced by large pointed-arch windows.

The 600 kg Christ-König bell from 1454 was destroyed in the war, and the church lost all its association and church banners plus the procession baldachin. Parishioners saved the interior during the 10 October 1944 fire, carrying it out while the roof burned.
