Classe is a town in the province of Ravenna. The current town of Classe has developed around the Basilica of Sant'Apollinare; it has very little to do with the ancient Civitas Classis that was situated to the north, close to the present course of the Fiumi Uniti rivers. Its name comes from Castrum Classis, which was the permanent encampment of the Roman fleet set up by emperor Augustus to control the east coast, although the reason for this particular position is still up for debate.
Between the 1st and 5th century a.d. the territory of Classe had many cemeteries; in one of these during the 1st century the first bishop of Ravenna - Saint Apollinaris - was buried. In the exact location of his martyrdom the Basilica di Sant'Apollinare, was erected in the 6th century, one of the eight UNESCO World Heritage sites of the city of Ravenna for its marvellous mosaics.
During the last century, in the small town of Classe there was also an important sugar factory, which was then left abandoned for many decades. Currently, the building is undergoing drastic restoration and is due to become the grand Archaeological Museum of the city of Ravenna.
