Green Citadel of Magdeburg

Along Breiter Weg in central Magdeburg, the site of the Green Citadel reflects successive phases of destruction, reconstruction, and urban change. St. Nicholas Church once stood here before suffering severe damage during World War II and being demolished in 1959. In the 1970s, an East German prefabricated concrete building was erected on the site. In 1995, Rolf Opitz, chairman of a local housing cooperative, invited Austrian artist Friedensreich Hundertwasser to redesign the existing structure. Rather than altering the concrete block, Hundertwasser proposed an entirely new building that would allow greater freedom for his architectural ideas. He continued developing the concept until his death in February 2000, after which architects Peter Pelikan and Heinz M. Springmann carried the project forward. Construction began in 2003, and the complex was officially inaugurated on October 3, 2005.

The completed building rises near Cathedral Square as an unconventional urban landmark. Its pink plaster facades follow irregular, undulating contours, interrupted by ceramic bands, mosaic-covered columns, and windows of varying shapes and sizes. Golden onion-shaped domes crown several towers, while planted roofs and terraces introduce vegetation across the upper levels. Two inner courtyards create sheltered spaces within the complex, with a fountain occupying the larger courtyard. The combination of curved walls, colorful surfaces, and asymmetrical details reflects Hundertwasser's rejection of rigid geometric uniformity and his preference for architecture shaped by individual expression.

Vegetation forms an integral part of the building rather than a decorative addition. Trees and shrubs grow from planted roofs, terraces, and openings in the facade, creating what Hundertwasser called Baummieter, or "tree tenants." These plants extend beyond the building's walls, allowing greenery to become part of its changing exterior appearance. The design also incorporates Hundertwasser's principle of Fensterrecht, or "window right," which gives occupants the freedom to personalize the exterior area surrounding their windows. The building's numerous windows differ in shape, proportion, and arrangement, reinforcing the idea that individual spaces need not conform to a uniform architectural pattern. Together, these features express Hundertwasser's belief that buildings should accommodate both human creativity and the natural environment.

Beyond its distinctive appearance, the Green Citadel functions as an active residential, commercial, and cultural complex. It contains 55 individually designed apartments, offices, shops, restaurants, an ART Hotel, the FriedensReich kindergarten, and a theater with approximately 250 seats. Its courtyards, public facilities, and guided tours allow visitors to experience the building beyond its exterior facades. As vegetation grows across the roofs and terraces, the relationship between the constructed surfaces and living plants continues to change. More than a sculptural landmark, the Green Citadel remains a functioning part of Magdeburg's urban life, demonstrating how Hundertwasser's architectural ideas were translated into spaces for everyday living, work, and public activity.
