There is one of the oldest amphitheatres built by the Romans, in Avella.
Until 1980 they were picturesque stone paths between the houses of a lively and populated village. For less then twenty years, these paths identified the location of ancient ruins, protected by a historical-archaeological park open to visitors.
On a hilly ridge between the Calore and Ufita valleys, Mirabella takes its second name from the ancient Aeclanum, whose site is in the Passo di Mirabella hamlet.
