It takes its name from the ancient Roman VADUM - Vadum also means "river port" - it was in fact an important place of trade and exchange on the Adige.
In fact, the river forked just upstream of Este and its secondary branch surrounded the whole of the Euganean Hills, lapping the Monte della Madonna to head towards Bovolenta where it met with the main branch and then flowed into the Adriatic.
In 589 during the Lombard domination, the river broke near Minerbe (VR) and left to flow freely in the plain the current riverbed was dug. The place, in the Middle Ages, gave rise to the noble family of "DA VO '" who owned a castle there; another castle, of the Maltraversi, stood in the locality of Castellaro but only a few ruins remain.
In the seventeenth century the Serenissima Republic of Venice, through the Contarini family, built the town of Vo 'Vecchio which was the seat of the Municipality until 1900.
In 1902, for logistical reasons, the municipal offices were moved to Vo 'Centro, the new chief of staff and placed in the Ca' Erizzo where they are still located.
On March 1, 1933 by order of the Provincial Council of Padua, what was previously called Ca 'Erizzo, was simply called Vo'.
The hamlets are Boccon, Cortelà, Vo 'Vecchio and Zovon. Ancient documents are found in Padua which speak of Boccon, Cortelà and Zovon before the year 1000.
A Roman plaque was discovered in Zovon and it seems that the town derives its name from a temple dedicated to the goddess Juno.
The god Bacchus, from which he took his name, would have been the protector of Boccon in which vines have been cultivated since ancient times. "Curtis-lata", that is Corte grande was the ancient denomination of Cortelà whose territory offers wonderful panoramas.
Vo 'Vecchio is a small town that represents one of the highest examples of urban planning organized on the layout of a Venetian villa, Villa Contarini, then Venier, from which it took its name which was later passed to the Emo Capodilista to finally become municipal property. The amenity of the places has favored the rise of some villas that enrich the artistic heritage of the town: 15th century Villa Ca 'Paruta, 17th century Villa Venier, 15th century Villa Ferro Ca' Lando, 16th century Villa Sceriman, Ca 'Morosini, Ca' Mariani from the 17th century.
In Vo 'the trachyte quarries are still active whose stone with different colors (gray, blue, green or with brown streaks), insensitive to the disruptive action of the atmospheric agents, was used in antiquity for columns, pavements, steps, coatings; now it is often used as an ornamental element that rises almost to a true work of art at the hands of the stonemason craftsman who sometimes knows how to raise himself to the level and dignity of the sculptor.
