In the sheet of water delimitated by these two buildings it was found a large cement quay, devoid of parameter, with a trampling surface made of irregular tuffaceous splinters which are nevertheless well flattened on a horizontal floor.

The north-western front is concave in the inferior part in order to mitigate the force of the sea and to protect the top of the quay from the waves. There is also, no more in situ, a mooring ring which proves that anciently the structure held out in the sea; so, besides being the basement of the upper villa, it provided also the possibility of anchorage.

On this floor, slightly moved back towards South, there are ruins of lateritious building structures in very bad conditions of conservation and of difficult interpretation in all the north sector of the building area as they are partially covered with their own collapse.  The level of legibility of the plant  improves in the central area of the building where it was possible to find out, for the presence of warmed environments, part of a thermal plant.
