Roman Amphitheater

The Amphitheatre of Catania is a Roman amphitheatre in Catania, Sicily, Southern Italy, built in the Roman Imperial period, probably in the 2nd century AD, on the northern edge of the ancient city at the base of the Montevergine hill. Only a small section of the structure is now visible, below ground level, to the north of Piazza Stesicoro. This area is now the historic centre of the city, but was then on the outskirts of the ancient town and also occupied by the necropolis of Catania. The structure is part of the Parco archeologico greco-romano di Catania.
