On 27 May 1409 Ottobuono de' Terzi, lord of Parma and Reggio, was murdered; his wife Francesca da Fogliano fled Parma in the first days of 1410 with three very small children, placed under the protection of the Republic of Venice, and came to settle here, where the documents give her the title of countess of the Valle. At Villa Bartolomea she met another widower, count Ludovico dei San Bonifacio of Lendinara, who had been a captain of arms for the Da Carrara and the Este and had fought beside Braccio da Montone, but who by now, sick of war, preferred humanist and theological studies. They married on 30 December 1417 and had six more children; and two of the children from their earlier marriages, his eldest and her youngest, married one another in their turn. That is how the San Bonifacio took root in this town.
Most of the territory lies in the Valli Grandi Veronesi, long threatened by the spreading marshes and held back only by embankments; modern reclamation turned it all into farmland and gave rise to the hamlet of San Zeno in Valle, which today is emptying again. The coat of arms, granted in 1872, shows a woman in a blue tunic holding in her right hand a broken chain, the symbol of liberty, and in her left a cornucopia, the symbol of fertility, with the motto In libertate labor. In the little church of the Madonna della Salute, built in 1920, the tiny bell tower holds two bells that came from war zones: one from Meolo, in the province of Venice, and one from Libya.
