Otto Mindhoff’s characteristic use of forms is brought to perfection in the facade of the Wildemannstraße car park. His monumental concrete relief covers almost the entire surface. A lengthier look shows that it consists of stylised depictions of cars and vehicles parts, reflecting the building’s function. Seen in this light, the striking flowing lines can be seen as conveying dynamism. The relief has been done in monochrome blue, the artist’s colour of choice.
