L'albergo delle Caldanelle di Petriolo tra XIV e XVIII secolo. contributo all'archeologia del termalismo in area senese

The hotel in the Caldanelle of Petriolo between the XIV and XVIII centuries. A contribution to the archeology of thermalism in the senese area · The archaeological investigations conducted on the Caldanelle site (Civitella Paganico, Grosseto) and undertaken by the Odysseus Association in 2018-2019, brought to light a rather complex settlement, whose purpose was to host travelers and swimmers who went there to benefit from the healing properties of the nearby thermal springs. These thermal baths are mentioned in some written reports of the fortification work on the site, promoted by Donosdeo Malavolti, Bishop of Siena, in the first half of the XIV century. The excavation campaigns led to the identification of four rooms, probably used for hosting the bathers, dating back to a period between the late XV century and the XVI century. The site was reportedly in use until the XVIII century. However, the stratigraphy of the elevations reveals the presence of fourteenth-century elements, which include the basement part of the outer walls with a door that was eventually closed off by an intentional action. Further investigations will better inform us about the division of spaces and the first stages of the foundation of the site.
