The city of Stuttgart, Germany has officially opened a marvelous new media center, the Stuttgart City Library. This cavernous white wonder is unobtrusive in design, where the books and visitors provide the color to an otherwise neutral environment. The visual center of the Stuttgart City Library is its grand atrium, a five-story open chamber that feels like the work of a modernist MC Esher. The interior is bright without direct lighting, it is warm without paint color and intimate yet open. This work by Yi Architects is a success in design, instantly one of the world’s most beautiful libraries.
