The porticoed courtyard represents the first public/private space, located immediately beyond the entrance threshold, through the large
, designed to imitate a large
and three vaults.
The courtyard has an irregular semicircular shape with a fountain in the centre and is surrounded on three sides by a porticoed colonnade, with Ionic style capitals. Its construction dates back to the Villa’s final phase of construction, when it was enlarged with new rooms; the great triapsidal triclinium and the ovoid peristyle in front of it were built and in geometric relation to the axes of these constructions, and the new entrance with the grand monumental portal was raised.
The courtyard provides connection and passageway, through its portico, for various entrances to the Villa: the entrance through the vestibule , the external access to the thermal baths and the space leading to the large external porticoed latrine , evidently for public use.
