Mosaics and residential complex
The excavations carried out inside the tholos (a circular structure, often a temple, of ancient Greece and ancient Rome) of the agora, in the south aisle of the Christian basilica and under the floor of a tomb in the southeast sector of the church have brought to light the remains of a polychrome mosaic depicting marine motifs with a frame of geometric bands.
This mosaic pavement pertains to a previous phase of the area demolished and levelled over when the agora was constructed. Due to its dimension and to the presence of two segments of a marble fountain visible under the tholos foundation, it is possible that the mosaic decorated the floor of an open court, with a fountain in the middle, pertaining to a residential villa of the imperial period.
