Discovered by Giuseppe Sordini in 1885 and brought to light with excavations that lasted until 1914, the Casa Romana was probably the home of Vespasia Polla, mother of Emperor Vespasian, as can be seen from a fragment found in the well of the house. The building is a refined aristocratic residence built according to the classical architectural scheme of patrician houses of the Roman era: it consists of an atrium complete with a basin for collecting rainwater, called 'impluvium', then there is the 'tablinum', the 'triclinum', the 'peristilium', 'cubicula' (bedrooms) and 'alae' (side rooms). All the rooms are decorated with splendid mosaic floors, and some still have traces of frescoes.
