The old Dome, dedicated to Santa Giustina, is a Romanesque-Gothic construction built from 1239-1250, consecrated in 1256, when it was still unfinished, and probably finished by the end of the century. The interior has a single wide nave, and ends with three apses of which the central has a cross vault. The central and left apse bear the polyptych of Santa Giustina and the Madonna of humility, respectively, paintings of the Venetian school of the fifteenth century. In 1361 at the parish church of Santa Giustina Francesco Petrarca received a canonical benefit.
