Urban Memory Theatre is a spatial installation that celebrates the architecture of Hong Kong. Using films as the primary medium of study, the work reviews the relationship between architecture, place and memory. This installation is not only a retrospective device, but also a machine to evoke thinking and imagination – for the possible future(s) of Hong Kong and its identities. This installation is inspired by the void spaces formed by the high-rise architecture of the city. It also pays homage to the model of Giulio Camilio’s Memory Theatre. The single person theatre is designed to submerge each individual into the “fragments of memory” of Hong Kong embedded into the lineage of movies across time. Movies with Hong Kong scenography are selected based on seven themes: City of Voyeurism, Shape of Consumerism, Changing Shoreline, Ultra-Connectivity, Temporality, Marginalised Space and Future Skyline. The “fragments of memory” are extracted and presented in different space forms, such as re-edited footages, mapping, extruded icon, condition models and imaginative models.
