The drama of collapse! Almost two years before the fall of the Wall, Berlin's 'Dripstone Cave' - the Großes Schauspielhaus designed by Hans Poelzig - was demolished. The Japanese architectural photographer Ryūji Miyamoto was by then already specialising in images of cities taken not during construction but in various stages of decline. He was on the spot in 1988 to document in film the phases of disintegration. It resulted in the dramatic stills which show columns revolving like ragged sculptures in a dance of death. It was the finale of an architectural icon: Berlin's nineteenth-century indoor market, which was occupied first by Circus Renz and later by Zirkus Schumann before Max Reinhardt opened Poelzig's Expressionist theatre grotto there with Aeschylus' 'Oresteia' in 1920. The end came when the pile foundations could no longer support the structure and the public streamed into the Friedrichstadt-Palast next door. Miyamoto's camera has also panned other locations of urban decay. He photographed the Cardboard Houses of the homeless in Tokyo and in Hong Kong's decrepit Kowloon Walled City, before an earthquake devastated the city of Kobe in 1995 and presented its ruins to the camera lens of this shocked eyewitness.
