‘Border hotels’ have come to prominence during the COVID-19 pandemic as spaces of detention and quarantine. Despite the longer history of using hotels for immigrant detention, efforts to contain outbreaks have led to the proliferation of hotels used for border governance. Ad hoc quarantine facilities have been set up around the world acting as choke points for mobility. The use of hotels as sites of detention has also gained significant attention, with pandemic related restrictions impacting on access to services for detained refugees and asylum seekers. Inhumane conditions and mobilisations against these conditions have recently received substantial media coverage. This symposium initiates a discussion about ‘border hotels’, closely engaging with these developments. Contributors document the shifting infrastructures of the border, and explore how these sites are experienced and resisted. They draw attention to divergent experiences of immobility, belonging, exclusion, and intersections of detention and quarantine. In exploring different - and controversial - aspects of ‘border hotels’, this symposium theorises modalities of governance implemented through hotels. Following in the footsteps of the ‘hotel geopolitics’ agenda (Fregonese and Ramadan 2015) it illustrates how hotels become integrated into border regimes. In doing so, it contributes to debates on the material and infrastructural dimensions of bordering practices and specifically to the literature on carceral geographies, polymorphic bordering and the politics of mobility.
