Many studies have found that the perceived authenticity of cultural and religious events affects event satisfaction and loyalty. Little is currently known about how perceived authenticity is affected by the quality of other event attributes, such as food and the availability of information, which are independent determinants of satisfaction and loyalty. This article explores this complex relationship using empirical data collected through a survey conducted during the 2010 Holy Year in Santiago de Compostela. A total of 400 questionnaires were analyzed using confirmatory factor analysis and structural equation modeling (SEM). The results of our analysis of the 2010 Holy Year provide support for the effect of event perceived authenticity on event satisfaction, and they also indicate that event perceived authenticity does not have a direct impact on event loyalty. Instead, its relationship to the intention to revisit is mediated by event satisfaction. In addition, the effects of event attributes were assessed for both event satisfaction and perceived authenticity, and significant differences were found.
