Property of the State only since 1986, the Villa of the Quintilii was the largest and grandest residence of the Roman Suburbium (environs). The original nucleus belonged to the Quintilii brothers, consuls in 151 CE, and was expanded after the Villa became imperial property under the Emperor Commodus.
Commodus loved to reside in it, because of the tranquillity of the countryside and of the benefits of the thermal baths housed inside the Villa. It spans the area between Appia Antica (Ancient Appian Way) and Appia Nuova (the modern road) and it is built around a big square. The most imposing nucleus of the building is the one consisting of the environments for the owners and those for the servants: a circular building, a series of rooms and the two large thermal chambers of the calidarium and the frigidarium, each 14 metres tall, with spacious windows and polychrome varieties of marble.
The monumental complex faces through a series of terraced levels the Roman Campagna and offers a view that over time inspired many celebrated artists.
