The Collére of Casolla: archaeology of the elevations of a proto-industrial bioclimatic system

In the Borough of Casolla located nearby Caserta, situated in the pre-Apennine area of Terra di Lavoro (Liburia in Latin), there is a large number of proto-industrial buildings used for the production of animal glue, between the end of the 18th century and the beginning of the 20th century. The driers of the glue factories (so-called collére) characterise the urban skyline, emerging with their long and high volumes from the mass of traditional buildings. In their ground rooms, preparatory activities were allocated such as raw material boiling and applying of the glue in sheets. Collére are monuments of the archaeology of work, material witnesses of the process of industrialisation of the territory, which offer further interesting elements from their unique concentration in the site examined. They are the most important environmental elements of this site, defining a specific cultural landscape, whose characterisation is correlated also with its economic, technological and social aspects.
