Work on the original Palazzo di Ezzelino began in the twelfth century, but the present-day appearance of the building would seem to date from the following century: evidence for this can be seen in its similarities with other buildings dating from the period of the Commune, and in the elegant two-light window on the first floor. Crowned with a crest in Vicenza stone dating from the fifteenth century, the building would be damaged by fire in 1760; and we know that in the years 1794-1873, the space above the wide facade vault was used as a theatre.
To the right of the palazzo – and of the facade vault that is also known as the Malvasia Vault – is a bronze plaque that commemorates Falvio Busonera, a member of the Resistance who was hanged here in 1944.
