St. Karl Borromäus

During the 1920s the population of Sülz grew sharply, so that the mother parish of St. Nikolaus still numbered around 30,000 members despite several spin-off parishes. On the site of a former gravel pit, a corner plot was acquired on which Pasmann and Bonn planned the church together with the surrounding residential buildings.

Ground was first broken on 30 March 1930, the foundation stone was laid on 9 June, and as early as 9 November of the same year auxiliary bishop Joseph Hammels consecrated the building. In 1950 the community was elevated to an independent parish. At the turn of the year 2001/2002 it merged with its former mother parish to form St. Nikolaus und Karl Borromäus.

The plain, rectilinear clinker-brick building with its simple gabled roof blends into the adjoining residential buildings in both height and façade material; only towards Zülpicher Straße do the north side and the tower open onto a small, slightly raised forecourt. Ornamental details recall Expressionism. Inside, since the 1967 redesign, a brightly plastered, pillarless single space extends from the gallery-topped vestibule to the choir. Sturdy concrete beams make possible the absence of supports and the raised, dark-blue-painted central axis; the raised altar area is lit by high-set windows.

The three-manual Seifert organ of 1954 has 37 stops and was completely overhauled in 1990/1991; its pipes stand freely in the space without a casing. The two-tone peal comprises a bell from the Otto foundry dating from 1924 as well as a Gothic "godparent" bell from 1521, with the strike tones D-sharp′ and F-sharp′.
