The idea of the open city has been used both conceptually and analytically to understand the politics of the city. The contrast between the open city and the closed city relies, in part, upon an understanding of the global systems that enfold cities and, consequently, the politics that are – and are not – afforded cities. Notions such as the postpolitical city depend not on temporality where the city has ceased to be political, but a spatialisation of politics where the (properly) political has become excluded by the closed systems that envelope cities. In this paper, we explore analytical and theoretical responses to the horror of the Grenfell Tower fire to disclose the ways that different critiques of neoliberalism and racial capitalism deploy and rely upon different conceptions of the open and closed systems of the city. Rather than settle for the open/closed binary, we seek to understand how different forms of openness and closedness afford/constrain the politicisation (and depoliticization) of city life – and its catastrophes.
