The adaptation of Palais Coburg revealed the archaeological secret lying dormant in its cellars: the largest surviving traces of Vienna's Renaissance fortifications. This dramaturgical concept interprets the walls' symbolic filtering of the outside reality from the inside illusion and the centuries-long physical, sociocultural, and psychological effect on the “City of Dreams”. Built upon the Braunbastei in 1840, the palace preserved a labyrinth of hidden tunnels, massive defensive walls, and a cavernous barrel-vaulted hall, vital clues in a biography retouched by the Ringstrasse make-up. The subterranean DNA combines with digital and analog installations to articulate a mental map of the entire defensive system for the visitors’ discovery of Invisible Vienna.

The two-faced mirror depicts the "wall" as a border and bridge, an import-export interface, and simultaneous window/filter of "otherness". Consisting of a row of back-to-back touchscreens, the extractions from the biographies of "inside" and "outside" personalities contextualizes the confrontation of cultures, religions, and politics that occurred at the walls throughout history. A GIS-mapping terminal developed by the MA7 city archaeologists portrays the overlapping layers of defensive fortifications, from the Roman settlement Vindabona to Hitler's decentralized network of flak towers.


In the 12-meter-high Wallhall the opposing big-screen 3D visualisations recreate two revealing periods in the Braunbastei’s history: the Turkish Siege of 1683 and Life on the Promenade in 1845. Complementing a sensitive restoration of the great barrel-vaulted hall, the seventeenth-century city plan is recessed into the new floor construction to relate the former walls to the existing streets and monuments. Bastionets – interactive islands extruded from the floorplan – provide detailed information about the visualizations and other stories related to the bastions. A city wall infopoint at the exit offers further information to encourage independent explorations of Invisible Vienna out in the city.
