Full of charm in the Roman Acropolis of Ferentino with buildings still intact. It rises on a grandiose terracing called by the scholars "southern avancorpo". The “avancorpo” is consisting of an imposing band of walls with a quadrangular plan. The interior has three rectangular rooms, surrounded by four corridors, covered in barrel vaults.
The large stones that make up the wall bandare stuck together without cement mortar.
The “avancorpo” rises from the ground for 33 feet, about 10 meters high. Aulo Irzio and Marco Lollio were the censors patrons of the great building work.
