St. Marien, Church building in Süderlügum, Schleswig-Holstein, Germany

St. Marien is a white-walled church with a steep gable roof on a sandhill in Süderlügum. Its Romanesque core was extended around 1500 with a longer choir and nave, and the flat beam ceiling was replaced by Gothic vaults. A small gabled porch, the Karnhaus of 1777, serves as the main entrance. Inside, two rows of red pews with blue panels line a black-and-white checkerboard aisle leading to a raised red platform with an organ in a red and gold case.

Built around 1200 as a Romanesque cemetery chapel and first mentioned in 1240, St. Marien served as a chapel of ease to Humptrup. Around 1500 the choir was doubled in length, the nave extended, and the Romanesque beam ceiling replaced by Gothic vaults. By the Reformation it had become an independent parish church.

The church bears the name of the Virgin Mary and its modest furnishings reflect the community's religious devotion over centuries. Visitors can observe old biblical paintings on the walls from the late 1500s that have been cared for by generations of worshippers.

Visiting is possible year-round since the church is actively used and hosts regular services. The building sits near the town center, making it easy to reach, and the surrounding area offers a quiet countryside feel.

Seven oval portraits of the Claudius pastors and their wives, painted around 1700 for an epitaph, hang on the south wall of the nave. The organ, built in 2015 by Marcussen & Søn, has 21 stops on two manuals and pedal and reuses the red-painted Rococo case of its predecessor.
