About 50km east of Ferrara, the Abbazia di Pomposa is one of Italy’s oldest Benedictine endowments. The monk Guido d’Arezzo reputedly invented the musical scale here, and in the 11th century it was one of Italy’s foremost cultural centres. Its decline began in the 14th century, and in 1652 vespers were sung here for the last time. The nave of its church has elaborate mosaic paving and is adorned with frescoes from the 14th-century Bologna school and artworks by Vitale di Bologna. There’s also a small museum.
