Themed spaces and theme parks constitute of significant human-based desires and linguistic discourses that stabilises/destabilises their social identities and materialities. This paper draws on a relational materialist perspective to examine Singapore’s longstanding themed space, Haw Par Villa, to offer insights into its social and material stability and instabilities. Relational materialism facilitates observations and analysis of interactions of humans and their material worlds on the same ontological plane where human’s agencies are de-centred. Social and material objects are seen to operate in mutually constitutive fashions. The development of a site/theme park and its larger country context are conceptualised here as ‘assemblages’ using DeLanda’s brand of assemblage theory to reveal the operations of human-based ‘desires’ alongside material agencies. Specifically, the desires of the founder and the key discourses related to the founder’s name helped constitute and stabilise the social identity and materiality of the Haw Par Villa through its eventful history of physical destruction, reconstruction, rebranding and reimagining. Despite his eventual non-involvement with Haw Par Villa’s management due to his passing, the founder’s desires and discourses linger on in various forms, resulting in subsequent attempts to rework the identity and materiality of this themed space failing if the attempts are not congruent on some level with the founder’s desires and discourses. This resulted in the failure of first, the state and, subsequently, private endeavours in re-constituting the themed space. In doing so, this paper contributes to a socio-material understanding of the resilience and sustainability of themed spaces.
