AbstractThis article explores one of the strangest and most spectacular urban policies in postwar Britain: national garden festivals. Initiated by Margaret Thatcher's government, the festivals were vast state-sponsored gardening shows held in deindustrializing cities to reclaim derelict land for the property market. A festival was held every other year between 1984 and 1992 in a different city, five in all. The garden festivals showcased a new kind of urbanism, one that would change the ways that British cities related to nature, to capital, and to the wider world. First, they evinced a unique type of environmental politics—an implicit critique of urban industrial landscapes that was distinct from both the emerging critique of climate change and from older ideas about conservation. Second, they emerged at a time when the attraction of private capital was becoming increasingly central to urban regeneration. The festivals were at the forefront of this turn, outsourcing their events to corporate sponsors. Finally, the festivals offered an idiosyncratic, incoherent version of globalization. They courted a global pool of tourists and capital and invited delegations from across the world to plan events while, in many instances, reinforcing a preexisting racialized social hierarchy shaped by imperial legacies.
