Our Laboratory carries out the reconstruction of green spaces of the past through archaeobotanical analysis integrated with evidence from other disciplines. For the Roman Period, research on domus of Modena and Forlì reported ornamental species, some frequently recurring (such as box, acanthus and myrtle); for the suburban area was rebuilt green furniture around a fish farming. The Middle Ages and Renaissance presents the most interesting cases: in Ferrara, the Giardino delle Duchesse of Este family, the green space of the Benedictine Monastery of S. Antonio in Polesine and the kitchen gardens of via Vaspergolo/corso Porta Reno; in Modena, the green space of the Bishop’s Palace. For the Modern Age it was investigated the Giardino dei Semplici of the Ospedale Maggiore of Milan and the gardens of Palazzo Giardino in Sabbioneta and Palazzo Te in Mantua. Some investigations have provided information on the history of important crops and ornamental plants.
