In a period still long before the great Este land-reclamation schemes, the Abbey stood on the Insula Pomposiana, a wooded island surrounded by branches of the Po and protected by the sea. This predominantly watery landscape, dotted with woodland and wetlands, formed an ideal setting for a monastic community devoted to prayer and work.
The origins of the complex remain partly uncertain: written sources mention the monasterium sanctae Mariae in Comaclo quod Pomposia dicitur in 874, while archaeological excavations have identified, beneath the medieval church, the structures of a small religious building perhaps dating to the sixth century. On the basis of this evidence, the main institutional websites place the formation of the first Benedictine settlement between the sixth and seventh centuries; between the eighth and ninth centuries it gradually took on the character of an important monastic community.
After the year 1000 the abbey entered its period of greatest splendour: under Abbot Saint Guido (1008–1046) Pomposa became a flourishing monastic centre, renowned for its manuscript production and for its prominent role in the circulation of people, ideas and models between the Po Valley, Ravenna and the Adriatic.
Over the course of the late Middle Ages the abbey’s power steadily declined, partly as a result of the waterlogging of the area linked to changes in the Po delta following the breach at Ficarolo (1152). With the consolidation of Este rule over Ferrara, the complex came firmly within the orbit of ducal power; after the Devolution of Ferrara in 1598 the entire territory passed to the direct control of the Papal States, and in 1653 the monastery was suppressed by Pope Innocent X.
The complex is organised into three main components: the church, preceded by an elegant atrium and flanked by the bell tower; the monastery; and the Palazzo della Ragione. The oldest core is the Basilica of Santa Maria (late 8th–9th century), but at an earlier stage there must have been smaller places of worship, now visible only through archaeological evidence. Beside the basilica stands the free-standing bell tower, built in 1063 by the master builder Deusdedit, which takes up and further develops the decorative language of the atrium.
Of the large monastery, what remains are the chapter house, the dormitory above it and the refectory, all looking onto the courtyard where the corner piers of the former cloister (12th century) are still visible and, at the centre, a Venetian wellhead dating from the 15th century. The Palazzo della Ragione (11th century), where the abbots administered justice over the lands under their jurisdiction, stands apart, facing the abbey, and was rebuilt – with alterations to the façade – between 1930 and 1931. Since 1977 the Pomposian Museum (Museo Pomposiano) has been housed in the former monastic dormitory and contains materials from the church and from parts of the complex that have been destroyed or altered.The surrounding area still preserves traces of the delta’s original landscape. Close to the Abbey lies the Canneviè Oasis (Oasi di Canneviè), the remnant of a larger system of coastal lagoons: a wetland of great ecological importance, equipped with paths and bird hides, which is a prime destination for birdwatching and nature-based enjoyment of the area.
