It is imaginable that during the Early Middle Ages the remaining habitation was restructured in connection with a modest early Christian sanctuary for the plebs, here to be located at the site of SS. Crocifisso. Although this sanctuary is only found in documents from the mid-12th century onwards, many early medieval spolia used in the later church of SS. Crocifisso indicate the presence of a much earlier phase. Around AD 1000 the population probably moved towards the more easily defensible hill-site of Montecchio (later called Treia) and the original town site remained practically deserted.
