ABSTRACT Rationale This article explores the development, use and impact of fan parks in host cities of men’s football mega events, constructed as temporary commercial sites where fans congregate to watch matches on large screens and partake in other forms of entertainment. Approach This study draws on ethnographic, observational, interview and focus group data, exploring perspectives of fans, volunteers, organisers, journalists, police and security personnel, totalling 212 respondents at five FIFA World Cup finals and ten other confederation tournaments. Findings This paper reveals that fans have increasingly engaged with such provision where available, relative to the degree of cultural resonance, accessibility, affordability, security and the suitability of facilities. However, these fan parks remain conspicuously absent in confederation events beyond Europe. Practical implications The research shows that fan parks can help diversify the fan experience, allowing users to interact with supporters from across the world in defined spaces. They also contribute to crowd management, enabling authorities to contain fans, confine their movement, monitor alcohol consumption and control behaviour. Research contribution This longitudinal study examines the emergence and development of fan parks at 15 events in five continents, analysing their impact on the fan experience and the securitisation of crowd management.
