This paper takes a multiple approach towards the study of the impact of Seville Expo 92. We start by identifying the social and cultural values of 50 professionals from the Sevilla, using the Hofstede model, adding some exploratory questions about the event, allowing understanding the perceived impact of the exhibition. We then have analyzed the Expo 92 reality through the case method by using longitudinal information. Results demonstrate how the socio and cultural values of Sevilla inhabitants have influenced the Expo 92 during its realization, but also after the event. Conclusions identify relevant con-tributions for future study on city events.
