Ancient Orraon was an impressive ancient citadel of Molossoi, which served both as a fortress and a waypoint for products handling.
It was founded in 4th c. BC on an especially strategic position – guarding the passage from the Amvracian Gulf to the basin of Ioannina. It was fortified with double walls, and at its peak was inhabited by 2000 people
In 168 BC Orraon was destroyed by the Romans. Its walls were totally grounded, because it was one of the four Epirus cities that resisted the Roman legions.
Orraon kept being populated until 31 BC, when it was abandoned and its inhabitants moved to the newly founded city of Nikopolis.
THE SURPRISINGLY GOOD CONDITION OF THE PRIVATE HOUSES OF ORRAON IS UNIQUE IN GREECE. THE MOST IMPRESSIVE EXAMPLE IS HOUSE 1, THE WALLS OF WHICH ARE PRESERVED UP TO A HEIGHT OF 5-7 METERS.
