A recently finished and very interesting project is the new entrance of the museum quarter ‘Joanneumsviertel’ in the center of Graz in Austria. The complex of the museum's buildings consists of two wings of the existing structure. For the connection of those old parts of the museum the architects designed the new entrance with two basement levels between them. The architectural challenge of this project was to bring daylight into these two lower floors. The concept of the architects was to let natural daylight flow in via vertical funnels in the form of small round courtyards with a diameter of up to approx. 16 m into the basement. Laminated and insulated glass was used for the cladding of these conically-shaped funnels.
