This book is the first volume to provide a comprehensive account of mega-event planning for the Paris 2024 Olympic and Paralympic Games. It offers a useful summary of the themes and debates relating to urban planning for the Paris Olympics, based on the results of a research programme (Observatory for Research on Mega-Event) funded by Gustave Eiffel University and Paris Est University and partly carried out with the organisers of the Games and their stakeholders. The authors address all aspects of the bidding process, the organisation of the Games and the construction of the social legacy of the Games.
