This study looks at the influence of place attachment on heritage discourse in contemporary places, specifically, Byzantine mosaics in Jordan, where the Byzantine Empire left behind a rich mosaic heritage. Today, these mosaics are replicated in contemporary architectural environments. The purpose of this article is to explore the heritage discourse surrounding Byzantine mosaics in Jordanian contemporary places with a particular focus on the replication and interpretation of the mosaics in contemporary places. To do that, the relationship between the attachments to the Byzantine mosaic places, the community’s level of awareness, and the replicated heritage discourse was examined. The research was conducted using several different methods, where structural equation modelling (SEM) was used to examine the relationship between these factors. Confirmatory factor analysis (CFA) was used to assess the measurement models of the latent components and examine their construct validity and reliability. In addition, the study was conducted in Madaba Archaeological Park in the Jordanian city of Madaba, known as the “city of mosaics”, which is rich in tourism and culture, as a subject of study. The results show that the phenomena of heritage replications in contemporary places rely on the expanding interest in history, which is manifested through realizing the historical value and unique features of heritage. This attachment, knowledge, and understanding of heritage sites based on socio-cultural norms help shape the discourse of heritage replication in the contemporary built environment. These findings provide an understanding of the reasons behind the replication behavior of heritage designs in contemporary places, which can be supported in future research and used to create an appropriate contemporary sense of place. In addition to the possibility of using it as a strategy for the sustainability of heritage designs in local culture and contemporary places, not only in Jordan but also in other heritage environments, finally, some useful suggestions emerge on which future research can be based.
