The archaeological area represents the first nucleus of the Archaeological Park of ancient Abella and contains the only monument that today is visited by the Roman city.
The amphitheatre, whose depiction appears on the side of a base of a limestone statue of the Antonine age now preserved in the square in front of the Ducal Palace in the historic centre of Avella, was built in the 1st century B.C. in the south-eastern part of the ancient city, in an area previously occupied by residential structures from the Samnite period.
The monument, in reticulated work, was built close to the city walls and supported, in the South-Western sector, by substructures designed to support the average and summa cavea, the latter not preserved.
