The Pomposa abbey is located about 50 km from Ferrara and 20 km from Comacchio, along the coastal Via Romea, traveled in the Middle Ages by pilgrims traveling to Rome. This area has been included in the Unesco sites since 1999, when the recognition already assigned to Ferrara in 1995 was extended to the territory including the Po Delta and the so-called Estensi Delights. The abbey complex is made up of three nuclei: the bell tower with the Church of S. Maria, the cloister with the annexed rooms and the Palazzo della Ragione. The church complex, characterized by the rectangular atrium with three entrance arches and the well-known bell tower, are the distinctive image of Pomposa. The Church today has a basilica plan with three naves with a polygonal apse, typical of the Ravenna environment, as well as many internal structural elements of Ravenna origin, from capitals to floor mosaics, which testify to the typically medieval practice of reuse, namely the reuse of valuable, older materials in new structures. The history of the Abbey is summarized in the Museum, a very interesting collection of artifacts and art objects from the 6th to the 19th century.
