Public space is partly what makes cities, and as such it has been at the core of urban studies and many disciplines ranging from sociology, geography, political science, anthropology to planning, architecture, design and philosophy. As one of the most multidisciplinary journals in the field, Urban Studies has been instrumental in exposing the controversies of public space during its 50 years of publication. A careful search through the archives of the journal, however, reveals that this interest has been rather uneven. While in the period before the 1990s a mere six articles dealt with aspects of public space, there has been a remarkable upsurge since then, which resulted in close to 300 articles. Somewhat paradoxically, the widely pronounced death of public space in the early 1990s thus marked the beginning of an extended debate on the topic of public space itself. This Virtual Special Issue (VSI) sets out to reinvigorate the debate once more in a critical synthesis of the important points that set the terms of the discussion and still reverberate in urban studies, by hoping to inspire new directions which touch on many disciplines. Using the death of public space as a counterpoint, the introductory article by Judit Bodnar reflects on the ‘life’ of public space, its cycles, forms and locations. It reviews the intellectual history of the main controversies that have kept discussions of public space alive, and further argues that attention to tensions, variations and comparisons can both reorient some of the fundamental questions of the debate itself and suggest research agendas for the future. The collection of 15 articles reflects first on the nature and specificity of public space, its historicity, its relationship to democratic politics, and then continues with the discussion of the most contested issues in the contemporary transformation of public space – privatisation, commercialisation and securitisation. Geographical diversity in the collection is not a mere gesture of politeness in a confessedly Western/Northern-dominated urban scholarship; nor is it simply driven by a desire to state that there are differences in the way public space is conceived of and operates in various places. Thinking about informality in Latin America, state and class in India, commercialisation in Vietnam, or security in other than North American ‘Western’ cities is meant to disrupt general urban theory and the public–private distinction.
