The Church of Santa Maria in Vado (Ford in English) was built close to such a ford, which crossed one of many canals intersected in this area. Its importance is due to a miracle of the Eucharist that happened on Easter Day in 1171. Apparently at the moment the church was consecrated blood erupted from the host, staining the apsidal vault above the altar. It was an instant place of pilgrimage and was enlarged from 1495 on an order of Duke Ercole I d’Este, who had commissioned the architect Biagio Rossetti to carry out the work.
