The project for a structural glass walkway originates from the plan of the Municipality of Pisa to connect two historical public buildings of the old town centre, respectively Palazzo Pretorio and Palazzo delle Logge di Banchi, see figures 1a) and b). The design, signed by arch. Roberto Pasqualetti, was developed by paying specific attention to the architectural and historical value of these two buildings. The basic idea is to build a footbridge that does not alter the Renaissance perspective of this area.
