Multiproxy archaeological investigation and Garden Archaeology in the Charterhouse of Calci (Tuscany, central Italy) and its territory : results and research data

A wide-ranging archaeological research programme at the Charterhouse and in the broader area of the Municipality of Calci has been performed since 2018. The archaeological research included the collection of legacy and aerial archaeology data, invasive and non-invasive investigations, as well as natural scientific analysis in the monastic complex. Special attention was paid to the archaeological investigations of three different monks’ cells gardens (the Prior’s, the Apothecary’s, and the Master’s), and stratigraphic excavations were combined with archeozoological and archaeobotanical analyses to define the horticultural practices implemented over the centuries of occupation of the Charterhouse. Among the three case studies, the most representative is the Prior’s meditation garden, where the excavation explored the phases prior to the construction of the building (14th century), the 18th-century renovation in the current form, and its abandonment at the end of the 20th century. Pollen analysis has allowed to reconstruct the richness of herbal species characterising an ever-blooming garden, with flowers and ornamental plants, such as roses, lilac, and water lilies, and also vegetables. According to charcoal and fruit-remain analyses, the Charterhouse exploited local hilly woods, satisfying the requirements of fuel by maquis and thermophilous deciduous forest. The agricultural practices included the cultivation of fruit trees, such as chestnut, olive, almond, and vine. Finally, archaeozoological analysis attests the domestic cat as the most frequent taxon in all contexts, probably common in the monastery as a pet and cell companion. This paper presents an overview and a discussion of the results of the investigations conducted and the complete archaeological dataset.
