Alt St. Katharina (Cologne-Niehl)

The "Niehler Dömchen": a 12th-century Romanesque basilica on the Rhine riverbank, featuring a Gothic choir and listed heritage status.

In the Cologne district of Niehl stands Alt St. Katharina — affectionately known as the "Niehler Dömchen" (Little Cathedral of Niehl) — a Roman Catholic church whose east-facing structure rises just beside the Rhine, separated from the riverbank only by the Niehler Damm.

Did you know?

The church served as the parish church for the entire area from Nippes to Niehl, but was replaced in 1892–94 by a new, larger building because it had simply become too small for the growing population – and has been affectionately nicknamed 'Niehler Dömchen' (Little Cathedral of Niehl) ever since, even though it remains in use to this day.

History

Niehl is first mentioned in documents as early as 927. The church traces its origins to a chapel of the Kunibert collegiate foundation, recorded in 1236. In 1260, auxiliary bishop Heinrich I of Montfort dedicated the high altar to Saint Catherine. The parish stretched from Nippes all the way to Niehl.

Architecture

The original 12th-century structure was a three-aisled Romanesque basilica with a west tower. Around the mid-13th century the choir was remodelled in Gothic style, while the south aisle disappeared; the nave received its vaulting around 1400. The sacristy was added around 1600, and in 1894 the north aisle was rebuilt on the original foundations.

New St. Katharina

As the congregation outgrew the old building, Theodor Kremer constructed the larger Neu-St. Katharina between 1892 and 1894 — a new parish church further south, more centrally located in Niehl. Sebastianstraße links the two churches. Several older pieces were transferred to the new building, including a carved Last Supper sculpture dating from around 1430.

Interior

The surviving furnishings include a pulpit bearing a relief of Saint Catherine, dated 1622, a crowned Madonna from the 16th century, and an 18th-century Crucifixion group. Later additions include two bells cast in 1977, choir windows by Vincenz Pieper (1978), nave windows by Dieter Hartmann (1988), and a six-register organ built by Gerd Weyland in 1982.

Today

A Mass is held on Friday afternoons, and on Wednesday mornings the neighbouring primary school holds a school service here. Thanks to volunteer helpers, the church is set to open its doors more frequently in the future.
