Introduction to the special issue – cultural mega-events and heritage: challenges for European cities.

The future of mega-events has never been more uncertain. The ongoing COVID-19 pandemic has introduced an unparalleled level of doubt regarding the kind of mega-events that will take place in the coming years. While the 2019 call for papers could not predict such a radical shock, this special issue arrives at a quite unique moment of reflection. Prior to 2020, cities were already questioning the traditional format of mega-events (e.g. Olympics and Expo) while other cultural mega-events have been spreading and gaining popularity, thanks in part to typically lower costs of infrastructures and venues, far more adaptable arrangements, spatial distribution and time frame for hosting. In these ways, they have already been demonstrating higher flexibility in which to respond to future health and safety constraints. When it comes to the relation to the existing city, cultural mega-events have been planned, implemented and studied far more than any other. By leveraging the richness of cultural mega-events, this special issue deepens the intersection between events and cultural heritage in particular. This introduction provides a theoretical framework that cuts across mega-event and heritage research fields. It introduces the questions and approaches of the following contributions, arguing that the nexus between mega-events and heritage is a key challenge for many cities in Europe and beyond.
