This area was investigated in 2006 during the construction of some technical rooms, and cleaned and further explored during the 2023 restoration campaign. You can see structures related to different life phases: the most recent is represented by the remains of the rectangular basin, presumably from the 18th century, which lies above other older wall structures that are difficult to date and interpret. Interesting are the two twin structures, interpretable as kilns for lime burning, as suggested by the finding of lime and stone residues all around; thus, it can be assumed that at least for a period this area was used as a working area for the construction of the monastic complex. A kiln is a structure designed for firing clay products (pottery, tiles, bricks) or, as in the case of this site, for producing lime from firing stones. Kilns that were used for lime are called calcare (lime). They are usually circular structures partly underground with a perforated roof, thick stone walls, and a small access point above ground. Limestone rocks were placed inside. In front of the entrance, at the base of the pile of stones, a space was created to light the fire and introduce the wood bundles; this also allowed air to enter to aid combustion. At a temperature of 800–1000°C, the limestone (calcium carbonate) loses carbon dioxide and transforms into ‘quicklime’ (calcium oxide). Quicklime combined with water produces ‘slaked lime’ (calcium hydroxide), which, when mixed with sand, forms mortar, a material used as a binder, for example, in the construction of walls.
