Chapelle de Saint-Clément, Romanesque church in Trechtingshausen, Germany.

The chapel is a Romanesque church in Trechtingshausen with three aisles, a flat-roofed main nave, and a rounded apse at its end. The structure shows typical features of this architectural style with narrow windows and arched openings that support the interior space.

The building was constructed in the middle of the 13th century as part of a parish under the administration of Kornelimünster Abbey. Its founding reflected the monastic institution's religious influence in the region during that period.

The chapel is still used as the cemetery chapel of Trechtingshausen, and its name comes from Saint Clement, to whom the former parish church was dedicated. Inside, fragments of medieval frescoes survive in the apse vault and the north aisle, and the interior colouring of the architectural elements was reconstructed after 1945.

The chapel sits near the old parish church and Saint Michael Chapel, forming a religious complex of buildings that visitors can explore together. The interior frescoes are best viewed during daylight hours when natural light illuminates the painted details on the walls.

The chapel is the southernmost example of Lower Rhine Romanesque architecture, recognisable by its trefoil clerestory windows and a blind rose window in the west gable. Its interior colour scheme was reconstructed after 1945, and the exterior plaster was restored during renovation at the end of the 20th century.
