This is one of the most luxurious complexes at the villa with floor and walls in opus sectile. It consists of four elements. On the north is the vaulted vestibule (4) and related rooms (5, 6). In the center is a quadriporticus garden (7, 8) with a canal (euripus) running down the main axis. At the south is a cenatio, perhaps also hosting a library (18-21, 30, 31, 37, 40, 41) and furnished with one-person latrines (23-28) disposed around a central, oval space (17) at the end of which is a nymphaeum (22). The complex could be reached either from the Hall of Doric Pillars or from a tunnel (1) with an exit into the cryptoporticus running under the quadriporticus (10-11).
