Choreographies, an installation at the 4th Lisbon Architecture Triennale by Pedro Alonso and Hugo Palmarola, presents the construction of building sites as cultural and political archetypes. By critically contesting comic films and animated cartoons released in the United States and the Soviet Union between 1921 and 1980, it presents construction sites as places in which ideology and imagination were combined through the choreographic movements of hanging steel-beams in the US, and flying concrete-panels in the USSR. These building components symbolize the construction of the modern world, the technological optimism of industrialization, the relevance of the building process over the completed building, and the standing of workers—welders, riveters and crane operators—against the vanishing figure of the architect.
