In the second half of the 19th century, Shamian was established and developed as a colonial island enclave in the Chinese city of Guangzhou. Simultaneously, literary and cultural imaginations, depictions, and narrations of the place produced a discourse of Shamian as a utopian island: geographically insular and bounded, environmentally beautiful and peaceful, socially exclusive and harmonious, and technologically progressive and advantageous. This paper examines contemporaneous (predominantly English) literary and cultural representations of Shamian as a colonial utopia and their interrelations with the island’s spatial formation and evolution. These texts (primarily written and pictorial descriptive, non-fictional accounts) reflected the spatial reality but also promoted spatial practices that reinforced the physical utopian island. This process exemplifies the theories of performative geographies in island studies and intertextuality in geocriticism, showing how a place’s spatial representations and reality are mutually constructed. Adopting a conceptual model of intertextual performative geographies, this paper investigates the dynamic interplay of these literary and cultural texts with the spatial reality, arguing that literary and cultural representations of Shamian (re)produced the colonial enclave as a utopian island, both conceptually and practically.
