Building History
The church evolved across several construction phases. A side nave with Gothic-style windows was added to the older central nave in the 15th century, followed by a tower built at the western end in the 17th century. This solid tower contained rooms that served as the sexton's living quarters for centuries.
Early Origins
During renovation work in 1925, early Christian memorial stones came to light embedded in the masonry. Such stones were typically used only in churches that held baptismal and burial rights — privileges reserved for parish churches — making an early Christian predecessor building possible, if not likely.
Maternus at the Helm
The chancel wall facing the Rhine holds a niche with a figure of Saint Maternus standing at a boat's tiller, holding a mitre in one hand. Passing sailors once directed their prayers to him. Below, a wave wreath frames the coat of arms of Rodenkirchen, featuring an anchor, Cologne's St. Peter's key, and the Berg lion. A Madonna from 1470 that once stood here has since been moved to the new church.
Life by the Water
Although the church and its adjoining churchyard sit slightly elevated, the building has never been spared from flooding. A protective wall was built around the church between 1764 and 1766, its foundations reinforced with oak beams and interlocking timbers. A small remnant of the churchyard that once surrounded the building survives nearby; its gravestones are heavily weathered, their inscriptions barely legible.
The Bell
A bell for the church was cast by Andreas Rodenkirchen in 1873. With a diameter of 411 mm and a weight of around 40 kg, it rings at the strike tone B♭5. The second bay of the small wooden bell frame remains empty.
