Models and moulds of terracotta architectural artefacts between Middle Age and 19th century: the challenge of three-dimensional digital modelling

The aim of this research is the comparison between real models and virtual ones, by evidencing the differences between the “authentic” architecture present on the territory and the “real model” of the Borgo Medievale. The model rebuilt by Alfredo d’Andrade reproduces complex decorative apparatus. The presence of nineteenth-century models, and their comparison, over a century has allowed to retain and transmit useful data for today's maintenance and restoration projects. It may be a new approach to reconstruction, through the production of "casts", which are made at a low cost. This is a path of knowledge that connects drawing, photography and photogrammetry as a documentation tool and more.
