The City Walls of Vicenza - Venetian extensions

After the brief period of the Viscontis (1387-1404), Vicenza fell under the dominion of the Venetian Republic. The city was further fortified in two areas: to the south-east beyond Borgo Berga beneath the slopes of Monte Berico, and to the north in the area of Borgo Pusterla.
The first stretch left from Porta Lupia (possibly Scaligerian), followed the present rise of Santa Libera, continued along Viale Risorgimento and turned along Viale Margherita. In this area it is still possible to see a few remains in private gardens. After Viale Margherita it joined the Piarda area, but its route is not certain, then beyond Porta Lupia, destroyed in the last century. Along this stretch there was Porta Monte, of which all that has remained is the name.
The second stretch was not built. All that was built was moats, Porta San Bortolo (or Bartolomeo), and five smaller round towers, two of which still existing along Viale Bartolomeo d'Alviano, named after the Venetian army commander who was responsible for having them built.
