Integration of knowledge-based documentation methodologies and digital information for the study of religious complex heritage sites in the south of Portugal

The progressive abandonment of religious houses, culminating with the Portuguese definitive dissolution of the religious orders in 1834, led to the alteration, abandonment or ruin of 131 religious complex heritage sites in the south of Portugal. This article defines a framework for their analysis, combining methodologies from different fields to obtain a more comprehensive understanding. After the settlement's identification, the literature review, the archival research, a census and morphological analysis of the existing physical structures has been carried out. The multidisciplinary framework is tested on a specific case study, including the production of 3D digital documentation and can be applied to the 131 convents. Findings can promote an increased awareness by nearby communities and public administrations, and encourage initiatives of heritage conservation, valorisation, and rehabilitation. Simultaneously, the study contributes to recognition of the importance of cultural heritage related to the analysed religious heritage sites, at local, regional and national levels.
