Dedicated multi media platforms have the potential to enhance experiences and increase people’s awareness of cultural heritage. It is, however, not clear to what extent and by which functions these platforms accomplish this. Therefore, the aim of this research is to investigate the influence of functionalities offered by a well-designed multi-media web-platform on the awareness and experience of cultural heritage. The multi media platform used is focused on Strijp-S, an industrial cultural heritage in Eindhoven, the Netherlands. The platform was created as a prototype based on a study of users’ preferences for contents and media types offered. To collect data, a sample of 302 respondents used the platform to explore and view Strijp-S. To test assumed relationships between different functionalities, awareness and experience in an integrated fashion, the data are analyzed using Structural Equation Modelling (SEM). The results show that information-collection funtionality plays a significant role in improving awareness of cultural heritage, whereas auxiliary functions are particularly helpful for enhancing experiences. The perceived helpfulness of these two sets of functions differ however between users depending on theitr level of prior knowledge. Policymakers and urban planners can use these results to create their own platform based on local heritage to increase the citizens’ awareness of cultural heritage.
