The south wing was the oldest and the richest part of the villa. It was provided with a 56 m. long and 5.5 m. wide colonnaded portico paved throughout with a geometric mosaic. Onto the portico opened a series of stately rooms and apsidal halls reminiscent of similar rooms in Roman palaces in Italy, Germany, or in rich Roman villas of Spain, France and England. They were used for official purposes and for decorative display.
