The location of Palazzo Zabarella is rich in history. Archaeological research in the 1980s and 1990s revealed the remains of a paleo-Venetian structure dating to the 8th century BC and the remains of mosaic flooring from the Roman era. The present complex, dating to the 12th-13th centuries, was used by the Carraresi until the end of the 14th century, when it was sold to the Zabarella family. The sale may have taken place in the final years of the 1300s as a corollary of the defeat of the Visconti, or in 1405, after the dissolution of the signoria. The complex shows both the strength and the sumptuousness typical of houses of the medieval aristocracy. The tower can be dated to the early 1200s, while the palazzo takes on the appearance given by 16th century renovations. The row of small arches under the crenulations definitely dates to the original construction. The interiors have been modified to meet more modern needs. Giacomo, last in the Zabarella dynasty, commissioned the decoration by three masters of the Neoclassical: Giuseppe Borsato (1771-1849), Giovanni Carlo Bevilacqua (1775-1849) and Francesco Hayez (1791-1882). The palace was a private residence until 1920, when it was purchased by Credito Veneto, who used it as the seat of the institution. After World War II it was used by the Casino Pedrocchi cultural and historical institute. Today the palazzo is the seat of the Bano Foundation, that organizes prestigious international art exhibits.
