A monumental photomontage rendered in gelatin silver print, Paul Citroen's *Metropolis* presents a dizzying, densely layered collage of towering skyscrapers, urban facades, and architectural fragments that overwhelm the senses with the relentless energy of the modern city. Created in 1923, the work captures the Weimar-era fascination with urban dynamism and the psychological intensity of metropolitan life. The stacked and compressed buildings create a vertiginous sense of scale, reflecting both awe and anxiety in the face of rapidly industrializing civilization.
