The Mariendom of Neviges, designed by Cologne architect Gottfried Böhm and consecrated in 1968, is one of the most striking examples of brutalist church architecture. Built to serve the growing pilgrimage to the Hardenberg image of the Immaculate Conception, its massive concrete structure rises in three interlocking tent-like forms, the highest reaching 34 meters. With its sharp angles, raw surfaces, and crystalline silhouette, the church embodies Böhm’s vision of architecture as sculpture, both fortress and sanctuary. Inside, a vast central space is bathed in light from colorful, irregularly shaped windows, their radiance contrasting with the heavy grey walls. The altar, placed at the heart of the building, gathers pilgrims in a forum-like setting. Artistic highlights include Marian and Sacrament columns, sculptures by Elmar Hillebrand, and a pipe organ installed in 2010. Accommodating over 6,000 people, the Mariendom is a monumental landmark of modern sacred design.
