As one of the most recognizable buildings along Vienna’s Ringstrasse, home to one of the most important art collections in the world, modifications to the Kunsthistorisches Museum are a delicate matter. To complicate things further, the museum’s café is prominently situated under an octagonal dome crowning the building. The design is organized around a series of polished brass halos hanging imperceptibly from the dome’s structure. The halos, which function as large chandeliers, reinforce the centrality and proportion of the domed space. Because of their concentric position relative to the central axis, they inscribe an inversion of the dome leading to the oculus at the center of the room. All other elements the room, such as benches, vitrines, and tables, are secondary circles or ellipses.
